24 Soil Testing - Soil Index Properties

Soil Index Properties

Soil index properties are used extensively by engineers to discriminate between the different kinds of soil within a broad category, e.g. clay will exhibit a wide range of engineering properties depending upon its composition. Classification tests to determine index properties will provide engineers with valuable information when the results are compared against empirical data relative to the index properties determined.

Determination of Liquid Limit

The condition of a soil can be altered by changing the moisture content. The liquid limit is the empirically established moisture content at which a soil passes from the plastic to the liquid state. A knowledge of the liquid limit allows the engineer to correlate several engineering properties with the soil. Two main types of test are used. The Casagrande type (Cup), which has been used for many years, and the cone penetrometer method, which is now the definitive method specified in BS 1377.

Casagrande Method

u Satisfies International Standards u Motorised version with integral blow counter available

Particular design features of the instrument include a positive action horizontal lead screw, which is rapidly adjustable and rigidly fixes the height of cup in relation to the base during the test procedure. The cam mechanism and cup suspension assembly have been designed to withstand constant use with minimum readjustment.

Cone Penetrometer MethodBS 1377, 1924-2, EN 1997-2

u Reduces operator erroru Applicable to a wide range of soils u Gives reproducible test resultsu Provides direct measurement of penetration

The method is fundamentally more satisfactory than the Casagrande method as it is essentially a static test depending on the soil shear strength. The test is based on the relationship between moisture content and the penetration of a cone into the soil sample under controlled conditions.

Determination of Plastic Limit BS 1377, 1924-2, EN 1997-2; ASTM D4318; AASHTO T90

The plastic limit is defined as the lowest moisture content of a soil that will permit a sample to be rolled into threads of 3 mm diameter without the threads breaking.

The test procedure has remained, in principle, the same since 1932, when Casagrande proposed to define the various limits by relating the moisture content characteristics of soil under certain conditions. The apparatus required is simple yet effective.

The majority of the apparatus required for this test is standard laboratory equipment. For full details see the Laboratory equipment section of the catalogue.

Determination of Shrinkage Characteristics

When the water content of a fine-grained soil is reduced below the plastic limit, shrinkage of the soil mass continues until the shrinkage limit is reached. Shrinkage can be significant in clays but less so in silts and sands.

The equipment listed below enables the engineer to determine a number of important parameters, including shrinkage ratio, volumetric shrinkage and linear shrinkage.

Volumetric ShrinkageBS 1377; ASTM D427; AASHTO T92

This method of test covers the determination of the shrinkage limit, shrinkage ratio, volumetric shrinkage and linear shrinkage.

Determination of Density, Particle Density and Specific Gravity

The term density refers to mass per unit volume. The density of a mass of soil is of interest to the engineer for a variety of reasons including the design of earthworks and foundations and in slope stability analysis.

Particle density or specific gravity is a measure of the actual particles which make up the soil mass and is defined as the ratio of the mass of the particles to the mass of the water they displace. A knowledge of the particle density is essential in relation to other soil tests. It is used when calculating porosity and voids ratio and is particularly important when compaction and consolidation properties are being investigated. The majority of apparatus used for the various tests is general laboratory equipment.

24 Soil Testing - Particle Size Distribution

Particle Size Distribution andSand Equivalent Value

The analysis of soils by particle size provides a useful engineering classification system from which a considerable amount of empirical data can be obtained.

Two separate and different procedures are used. Sieving is used for gravel and sand size particles and sedimentation procedures are used for the finer soils.

For soil containing a range of coarse and fine particles it is usual to employ a composite test of sieving and sedimentation procedures.

The Sand Equivalent Test serves as a rapid field test to show the relative proportions of clay-like or plastic fines and dusts in granular soils and fine aggregates.

24 Soil Testing - Compaction and CBr

Compaction

Many civil engineering projects use soils as fill material, with soil normally being compacted to a dense state to ensure that it has the optimum properties.

Compaction on site is generally achieved by mechanical means such as rolling, ramming or vibrating. Precise control over the level of compaction is essential to achieve best results at reasonable cost, with laboratory compaction tests being used as they provide the basis for control procedures that are subsequently used on site.

Compaction tests typically enable the following criteria to be established:

u The relationship between dry density and moisture content for a given degree of compactive effort.

u The moisture content for the most efficient compaction; that is, at which the maximum dry density is achieved under that compactive effort.

u The value of the maximum dry density achieved. There are several different standard laboratory compaction tests, with the most appropriate in each case being based on the nature of the project, the type of soil and the availability of equipment on site.

Applications of Compaction

Soil used as fill:

u To refill an excavation or voidu To provide made-up ground to support a structureu As a sub-base for a road, railway or airfield runwayu As a structure; e.g. an earth dam

Improvement by compaction

u Higher stability u Higher CBR Valueu Lower compressibiltyu Lower permeabilityu Lower frost susceptibility

Effect on mass of fill

u Greater stabilityu Less settlement u Less deformation u Less water absorptionu Less risk of frost heave

The time and effort required to prepare specimens for compaction studies and other test methods can often be costly and time-consuming. The use of an automatic, mechanical compactor will show considerable cost benefits over hand compaction methods. Two models meeting the requirements of BS/EN and ASTM are available.

Automatic Compactor BS1377, EN 1997-2, 1924; ASTM D558, D560, D698, D1557; AASHTO T99,T134,T135,T136,T180

u Pre-set blow pattern ensures even compaction u Solid state controls for reliability and ease of maintenance u Automatic re-setting of counter after completion of blow pattern

These machines automatically compact specimens eliminating the laborious hand compaction method. The height and weight of the rammer are adjustable to suit test requirements. An automatic blow pattern ensures optimum compaction for each layer of soil. The rammer travels across the mould and the table rotates the mould in equal steps on a base that is extremely stable. The number of blows per layer can be set at the beginning of the test.

The California Bearing Ratio test, or CBR test as it is usually termed, is an empirical test first developed in California, USA, for estimating the bearing value of highway sub-bases and sub-grades. The test follows a standardised procedure and there is little difference between BS/EN and ASTM tests. However, there are numerous ways of preparing samples and in this respect American practice differs in detail from British practice.

This test can be performed in the laboratory on prepared samples or on location. It is important to appreciate that this test, being of an empirical nature, is valid only for the application for which it was developed, i.e. the design of highway base thicknesses.

California Bearing Ratio A number of options are available to collect and analyse data with the ELE CBR-Test 50.

25 Soil Testing - Consolidation

It is generally understood that clays and other compressible soils can be subject to long-term consolidation under the loads imposed by foundations and above ground structures. Also that settlement may occur even if the applied pressure is within the safe bearing capacity of the soil.

Traditionally, consolidation has been measured with an oedometer and this is generally known as the one-dimensional consolidation test. We provide a range of standard consolidation test equipment, with purpose-written software for precise and fast statistical analyses, plus specially designed pneumatic and hydraulic consolidation cells, together with a wide choice of options.

Consolidation


26


One-dimensional Consolidation

The One-dimensional Consolidation test is used to determine the consolidation characteristics of soils of low permeability. Tests are carried out on specimens prepared from undisturbed samples. Data obtained from these tests, together with classification data and a knowledge of the soils loading history, enables estimates to be made of the behaviour of foundations under load.

25 Soil Testing - Permeability

Permeability

Knowledge of the permeability characteristics of soil is essential for construction projects where drainage is an important element. In particular, permeability is a key parameter for the design and assessment of landfill sites, the investigation of contaminated ground, the design of earth dams and sheet pile walls, and in assessing the potential for lowering groundwater levels.

In many applications, the use of a flow-net analysis together with permeability data enables both the rate of seepage of water through or under a structure to be estimated, and seepage pressures to be calculated.

In each case, we offer a full range of testing equipment including:

Constant Head Apparatus BS 1377; EN 1997-2; ASTM D2434; AASHTO T215

This equipment is used for testing the permeability of granular soils (sands and gravels).The specimen is formed in a permeability cell and water is passed through it from a constant level tank. Take-off points located along the sides of the permeability cell are connected to three manometer tubes mounted on a panel complete with a metre scale. Water passing through the specimen is collected and measured, either for a specific quantity or over a period of time. The reduction of head is noted from the variation of water level in the manometer tubes.

Falling Head Apparatus

Clays and silts are tested using the falling head technique. Flow of water through the specimen is observed by monitoring the rate of fall of water in the tube. It is essential that soils of very low permeability are sealed inside the cylinder to prevent seepage along the sides of the specimen. Before testing, the specimen must be completely saturated with water as the presence of air will restrict the flow of water.

Combination Permeameter CONSTANT Or FALLINg HEAD METHODS

u Plated steel chamber head assembly u Corrosion-resistant cast aluminum base assemblyu Includes accessories for conducting both constant and falling head permeability studies

This combination permeameter has a transparent plastic chamber for soil specimens of either fine-grained or coarse-grained soils. Generally, soils containing 10 percent or more particles passing a 75 µm sieve are tested using the falling head assembly. More granular soils, containing 90 percent or more particles retained on the 75 µm sieve, are tested using the constant head assembly.

The cell is sealed at the top so that a vacuum may be used to saturate the specimen. Porous stones located at the top and bottom of the cell prevent sample flaking or washout.

For constant head tests, a plastic funnel reservoir is mounted on an upright attached to the cell, providing a maximum head of 550 mm. Falling head tests are performed using the graduated pipette falling head reservoir, which gives a maximum head of 1000 mm and is graduated 0.2 ml.

25 Soil Testing - Soil Strength (Triaxial)

Soil Strength (Triaxial)

The measurement of total stress or effective stress requires different procedures and therefore different equipment.

Total stresses are normally measured in a triaxial cell where the sample is subject to an all round confining pressure ( 3). A load is applied ( 1) through a piston onto a pressure pad, with the sample being confined within a rubber membrane so that no drainage in or out of the specimen is allowed. Pore water pressures are not normally measured and the undrained test is often referred to as the QU-TXL test.

An extension of the QU test is the unconsolidated undrained test (UU); this is similar to the QU test but is run at a slower rate in order to measure pore water pressure.

By comparison, effective stresses when measured in a triaxial cell are more complex in their nature, as numerous parameters can be measured. These include back pressure, pore water pressure and volume change; all of which can be used to calculate the required engineering properties.

Effective stress tests are usually referred to as consolidated drained (CD) or consolidated undrained (CU). Generally the CD test is applicable to sands, while both the CU or CD test can be used with clays. There are many special test variations within these basic test groupings.

Our range of triaxial cells and accessories, used in conjunction with other equipment such as load frames, pressure sources and measurement devices, have been specifically designed to meet the wide ranging requirements of modern soil mechanics laboratories. Each system is easy to set up and use, providing accurate and repeatable measurements.

u Large on-board LED screen display u Fully variable speed, 0.5 to 50 mm/minuteu Rapid and momentary approach of platenu Mechanical or electronic measurementu Triaxial samples up to 100 mm diameter

This 50 kN capacity machine has been designed primarily for performing laboratory CBR, Marshall stability and quick undrained triaxial tests on one load frame. It is particularly suitable for those laboratories carrying out a mix of these tests, e.g. for road construction. The compact bench mounting design comprises a twin column frame incorporating a motorised drive system. A robustly constructed case houses the drive system, with careful attention being given to the prevention of ingress of water or grit. All operating controls are mounted on the front panel of the machine.

Electronic measurement is achieved using the optional EL27-1200/09 Electronic Control and Readout Unit (ECU) and appropriate load and axial displacement transducers, see catalogue Section 27. With digital readout, data logging capability and download software included as standard, the Multiplex 50/ECU combination provides unique features safeguarding not only the testing equipment, but also test integrity and accuracy.

Among these, the ECU will check its testing mode (CBR, Marshall, etc) against the frame speed setting and will not permit the test to run if these settings are incompatible. The ECU automatically configures its logging rate for each test type to comply with BS, ASTM or AASHTO Standards. This means the data exported from the ECU needs no further manipulation before analysis and reporting. Finally, if the upper limits of the transducers are exceeded, the ECU stops the load frame to protect the test accessories and load frame drive system.

This range of precision made triaxial cells has been designed to meet the requirements of the modern soils laboratory. The cells have been treated to minimise corrosion. Particular attention has been paid to the quality of finish between the piston and the head. Final assembly includes the fitting of an O-ring seal and the use of special lubricant to reduce friction to a minimum and eliminate water leakage.

The piston load capacity is designed to accept high horizontal forces which may be present during the final stages of a test.

Each cell has five take-off positions drilled in the base for top drainage/back pressure, pore water pressure and bottom drainage.

Two no-volume change valves and an anvil for strain gauge/transducer datum are supplied for fitting to the cell.

A feature of these cells is that they all accept a single diameter piston. The internal height is such that a range of submersible load transducers can be fitted without any modification. Each cell will accept a range of base adaptors and various accessories for testing a wide range of specimens.

De-aired Water

It is particularly important that water from which dissolved air has been removed is used in the pore pressure measurement system and saturation procedures. Any dissolved air in the water will lead to errors in the measurement of pore pressure, particularly at low pressures, and also give slow or incorrect saturation results.

ELE De-aired Water Apparatus BS 1377

This compact self-contained unit will de-air water quickly and efficiently down to levels of dissolved oxygen acceptable for geotechnical test methods.

Air is removed from the water by a vacuum system, which continuously circulates the water in the tank.

26 Soil Testing - Pressure Systems

Pressure Systems

The provision and use of constant pressure systems in the geotechnical laboratory is essential if testing methods and equipment are to be fully utilised. Generally a number of independent and variable pressure sources will be required in a laboratory. Accurate and reliable monitoring systems will also be required, which may range from a single pressure gauge through a whole series of transducers.

We offer a range of products designed to supply and monitor all those parameters necessary for the successful testing of geotechnical materials. Two types of constant pressure systems are available:

1. Air/water system operated by a pneumatic compressor 2. A motorised oil/water system

Air/Water Constant Pressure System

Where a laboratory requires a number of constant but independent and variable pressure sources, the use of a pneumatic compressor is recommended. Depending on the capacity and volume of the unit, a series of pressure sources can be provided to various test stations around the laboratory. Two sizes of compressor are available.

Ordering Information700 kPa Air Compressor Unit see EL83-1730/01

26 Soil Testing - Direct Shear and Vane Tests

44

Direct Shear and Vane Tests

Every building or structure that is built in or on the earth imposes loads on the soil supporting the foundations. The stresses set up in the soil cause deformation of the soil with stress failure being caused by slippage of soil particles, which may lead to sliding of one body of soil relative to the surrounding mass.

The process is known as shear failure and occurs when shear stresses set up in the soil mass exceed the maximum shear resistance that the soil can offer, i.e. its shear strength.

29 Soil Testing - Bearing Capacity

Bearing Capacity

The design of foundations is a prerequisite of economic design and construction. In order to guard against shear failure and unacceptable ground movements due to loading it is often necessary to determine the ground bearing capacity.

Dynamic Cone Penetrometer

The TRL (Transport Research Laboratory) Dynamic Cone Penetrometer (DCP) is used for rapid in-situ measurement of the structural properties of existing road pavement constructed with unbound materials. The unit incorporates an 8 kg weight with a drop of 575 mm, and a 20 mm diameter cone fitted to the end of the shaft, allowing measurements to be made down to a depth of approximately 850 mm.

Readings are usually taken after a set number of blows, changing the number according to the strength of the layer being penetrated. For good granular bases, readings every five to ten blows are satisfactory, but for weaker sub-base layers and subgrades, readings every one to two blows may be appropriate.

The DCP requires three operators, one to hold the instrument in a vertical position, one to raise the hammer and let it fall and one to record the results. A typical test takes only a few minutes, providing a very efficient method of obtaining information which would otherwise require the excavation of test pits. Where pavement layers have different strengths, boundaries can be identified and layer thickness determined.

SpareEL29-3720/10 Replacement Cone

Pocket Penetrometer

A lightweight device for determining the approximate unconfined compressive strength and the estimation of shear strength, it can also be used to classify cohesive soils in terms of consistency.

The stainless steel plunger is pushed into the soil until the penetration mark is reached. The equivalent unconfined compressive strength of the soil can be read in kgf/cm2 or tons/ft2 from the maximum load indicator provided.

Important: the readings obtained from the pocket penetrometer do not replace laboratory test results due to the fact that a small area penetration test is inherently liable to give misleading results. The instrument should not be used for obtaining foundation design data.

29 Soil Testing - In-situ Density

In-situ Density

Many civil engineering projects require the use of fill material. Whenever soil is placed as an engineering fill, it is usually compacted to a dense state, to obtain satisfactory engineering properties. Compaction on site is usually effected by mechanical means such as rolling, ramming or vibrating. Control of compaction is necessary to achieve a satisfactory result at reasonable cost. Laboratory compaction tests provide the basis for control procedures used on site.

Proctor Penetrometer ASTM D1558

This spring-type penetrometer can be used in the field to control soil compaction. The stem is calibrated to 150 lbf x 2 lbf divisions, and a sliding collar indicates the applied load. A rapid estimate of the moisture content of soil can be obtained by comparing the amount of penetration of the needle for a corresponding load, with a laboratory determined moisture/density curve for a similar soil.

Concrete

What is Concrete?

Concrete is perhaps the most versatile of all construction materials. In its freshly mixed condition it can be poured, pumped and moulded into a variety of forms and shapes, while in its hardened state it can be used for many construction purposes.

The quality of concrete is crucial if structures are to be safe and serve the purpose for which they were designed. Our concrete testing equipment gives you the ability to measure and prove the quality of each batch of material, so that you can ensure the correct application of the key raw materials.

Cement

Cement is a man-made material and can be supplied in many forms, with different cements having specific and often varied properties, such as rapid hardening, sulphate resistance and low heat.

The precise cement content for different batches of concrete will normally be specificed at the time of manufacture; typically, concrete has a cement content of about 250 kg/m3.

Sections 38 and 39 describe test equipment specifically designed for the testing of cement.

Aggregate

By far the greatest proportion by volume of concrete is made up of aggregate. This can be naturally occurring, such as river gravels, or crushed rock from quarrying operations; other materials can also be substituted for aggregate including colliery waste and recycled concrete.

Normally, coarse and fine aggregates are used in the proportions of approximately 70:30.

Section 42 describes test equipment suitable for the testing of concrete aggregates.

Water

Water reacts with cement and allows the necessary hydration and hardening process to proceed. The quality of water is not generally critical providing it is clean and free from impurities and high silt content. The quantity of water added does, however, have a major effect on the quality and strength of the concrete.

Test equipment designed to determine the effect of water on fresh concrete is described in Section 34.

34 Concrete - Fresh and Hardened Concrete Testing

Sampling, Consistency and Workability

The correct sampling and mixing of fresh concrete is important if test results are to be reliable. Most of the equipment necessary for efficient sampling and mixing is standard laboratory equipment detailed in the Laboratory Equipment section of this catalogue.

To ensure that concrete achieves its maximum possible strength and yet retains its ease of placing on site, it is essential that the design of the concrete mix, in relation to the water-cement ratio and workability, is closely controlled.

Slump TestEN 12350-2; ASTM C143; AASHTO T119

u Test is appropriate for concrete mixes of medium and high workability

The test is carried out by filling the slump cone with freshly mixed concrete, which is tamped with a steel rod in three layers. The concrete is levelled off with the top of the slump cone, the cone removed, and the slump of the sample is immediately measured.

Vebe TimeBS EN 12350-3

u Test appropriate for concrete mixes of low and very low workability

This method is a mechanised variation of the slump test and includes a determination of the workability of concrete. It is based on the principle of subjecting the concrete to vibration after removal of the slump cone. The assembly is mounted upon a small vibrating table operating at a fixed amplitude and frequency. The time to complete the required vibration gives an indication of the concrete workability.

Special Note: The consistometer must be operated from an electrical supply of 50 Hz in order to comply with the fixed test frequency specified.

Air Entrainment

The determination of air content of freshly made concrete is detailed in EN 123450 and ASTM C236, where the importance of two main applications is highlighted. The primary purpose of entraining air in concrete is to give the required resistance to weathering. The use of chemical additives to increase the workability of concrete often requires an air content check to be made.

Mixing Equipment

The efficient mixing of concrete prior to moulding specimens in the laboratory for subsequent testing is essential if quality specimens are to be manufactured. The object of mixing is to coat the surface of all aggregate particles with cement paste, and bring the mix to a uniform condition. Pan or rotating drum mixers are suitable for the mixing of small quantities of concrete, which are generally used in a laboratory.

Moulding Equipment

Test procedures require that specimens are cast in a number of standard sizes convenient for compressive and flexural strength determination. The engineering tolerances specified for moulds are very stringent and the internal finish of the surface must be of a high order to comply with the recommendations laid down in many International Standards. Moulds must not deform during manufacture of concrete specimens if the specimen dimensions are to be maintained.

Compaction

The strength, durability and finish of concrete rely in part on the adequate compaction of the mix. An increasing number of contract specifications call for various forms of vibro-compacted concrete as a means to achieve a better and more consistent mixture. It should however be remembered that fluid mixes may segregate when vibrated in which case it may be more appropriate to compact using a tamping bar or rod during laboratory mix design.

The ELE vibrating table is a compact unit providing controlled vibro-compaction in the laboratory, using cube or cylinder moulding equipment.

Curing of Specimens

The correct environment for curing concrete test specimens is important to achieve consistent and reproducible test results. Two primary factors must be taken into consideration to satisfy the requirements, namely to maintain a stable temperature and to prevent loss of moisture from the specimen.

A standard curing temperature of 20ºC is usually specified and should be maintained at the required degree of accuracy. The use of water to prevent loss of moisture is the method most commonly used. In tropical climates a curing temperature of 25ºC is often acceptable.

Large Curing TankEN 12390-2, ASTM C31, C192, AASHTO T23

This curing tank is supplied complete with a submersible pump, immersion heater/thermostat unit and separate control panel.

Capping of Cylinders

When conducting a compressive strength test on a concrete cylinder it is important that the ends of the specimen are flat and parallel to each other. The trowelled face of a prepared concrete cylinder, or both ends of a concrete core, will require treatment to obtain these conditions.

Sulphur Compound MethodEN 12390-3

The sulphur compound method is a hot process and offers a considerable saving in time and labour over the mortar capping method. The method is virtually instant and the compound can often be recovered for further use.

Warning: The sulphur compound, when hot, will give off sulphur fumes, and therefore it is important that good ventilation, or preferably a fume cupboard, is available in the laboratory.

Density of Fresh and Hardened Concrete

The density of both fresh and hardened concrete is of interest to the engineer for numerous reasons including its effect on durability, strength and resistance to permeability.

Hardened concrete density is determined either by simple dimensional checks, followed by weighing and calculation, or by weight in air/water buoyancy methods.

Density of Hardened Concrete EN 12390-7, 1097-6

The density of hardened concrete specimens such as cubes and cylinders can be quickly and accurately determined using a Buoyancy Balance.

Buoyancy Balance

The buoyancy balance system developed by ELE consists of a rigid support frame, incorporating a water tank mounted on a platform. The water tank has internal dimensions of 380 x 240 x 280 mm (l x w x h).

A mechanical lifting device is used to raise the water tank through the frame height immersing the specimen suspended below the balance. The balance supplied calculates the specific gravity of the sample automatically.

The balance may also be used as a standard weighing device, thus providing a versatile and comprehensive weighing system in the laboratory.

Drying, Shrinkage and Moisture Movement

The apparatus has been designed and manufactured to the recommendations laid down in BS, EN and ASTM standards where tests are required on laboratory specimens, or on specimens taken from existing structures. The test procedure specifies a method for determining the change in length of a concrete or mortar sample brought about by a change in moisture content.

1 Initial drying shrinkage: the difference between the length of a moulded and cured specimen (under specified conditions), and its final (constant) length when dried.

2 Drying shrinkage: the difference between the length of a matured specimen cut from concrete and saturated, and its final (constant) length when dried.

3 Moisture movement: the difference between the constant length of a specimen when dried, and its length when subsequently saturated with water.

Pulse Velocity Measurement

The basic principle of this method of testing is that the velocity of an ultrasonic pulse through concrete is related to its density and elastic properties. Some care is necessary when testing, but an experienced operator may obtain a considerable amount of information about a concrete member. The advantage of this method is that the pulse passes through the complete thickness of the concrete so that the significant defects can be detected. Applications

Flexural and Transverse Testing Machines and Accessories

The flexural and transverse strength of concrete is of interest to engineers for many reasons. Movement of structures which may be induced by e.g. temperature changes, ground vibrations, cyclic loading of road pavements and many other external influences, will set up internal stresses within a concrete member.

There is no clearly defined relationship between compressive and flexural strength. Generally it can be assumed for most purposes that flexural strength of normal concrete is about 10% of the compressive strength achieved in the same concrete.

Modern concrete technology utilises a wide range of materials such as glass or steel fibres to improve the flexural strength of the concrete. These modified concretes often require the use of special tests and equipment.

Lower loads are used to test concrete in flexure; however, the shape and size of test specimens is such that larger and often heavy specimens can be difficult to handle. ELE has designed the range of machines offered to provide for ease of specimen positioning and subsequent testing.

The range of flexural test equipment offered provides a wide variety of choice and test methods including low strength compression tests using optional ball seating assemblies.

The first use of lime as a cementing material is not recorded but it was certainly used in ancient Egypt and also by the Romans. In more recent times, there are records that lime, combined with a pozzolan from Italy, was used in the construction of the Eddystone lighthouse as early as 1756.

Today, cement is manufactured by a chemical process with raw materials being crushed, ground and blended before being heated in a rotary kiln until they combine chemically. The clinker from the kiln is then ground with gypsum to form Portland cement.

Our cement testing systems provide efficient and reliable methods of measuring all of the key criteria to ensure consistent, high quality cement manufacture.

38 Cement - Fly Ash

Fly Ash Fly Ash or Pulverised Fuel Ash (PFA) is a by-product of coal-fired power stations. It is a fine material with spherical particles. Uses include as an additive in composite cements, as a cementitious component in concrete and as a filler in certain types of asphalt.

Various test methods are specified in BS and EN Standards and include the determination of moisture content, water requirement, strength, loss-on-ignition, initial setting time, and soundness. These tests are based on those described in BS EN196. A major requirement for Fly Ash is consistency of fineness.

Loss-on-IgnitionEN 450

This method is for cement specified in EN196-2 with an ignition time of 1 hour at 975ºC.

Muffle Furnace see Laboratory Equipment Section

Activity Index EN 450

39 Cement - Mixing, Moulding, Curing and Strength

Mixing The results of strength testing of cement and other materials such as Lime and Fly Ash are dependent on the method and the quality of equipment used. A standard system for strength testing is based on compressive strength of mortar prisms.

In the USA, ASTM C109 and C190 are the definitive methods for determining compressive and tensile strength. The BS 4550 method using either 70.7 mm or 100 mm cubes has been retained in the UK only for comparative purposes. EN196-1 is now the definitive method.

The results of strength testing are dependent not only on method but also on the quality and accuracy of the testing machine used to determine compressive or flexural strength.

The correct mixing sequence and homogenity of mix is important if consistent, repeatable test results are to be obtained. Mixers should be powerful enough to ensure that the motor’s speed is not affected by the mix constituents and designed to ensure that the mixer action and blade does not break down individual sand particles and preferably provide automatic mixing cycles.

42 Sampling and Preparation42 Particle Size and Shape42 Determination of Flakiness and Elongation42 Density, Voids and Bulking 42 Soundness and Chemical Tests 42 Mechanical Properties

Aggregates comprise a significant proportion of all materials used in the many different construction processes, so it is important to determine the properties of different types of aggregates through effective testing and measurement.

The required properties will vary from project to project, for example, resistance to polishing will be unimportant in a pavement base course but will be crucial in a wearing course. However, the key criteria throughout are accurate and repeatable test procedures, and our range of aggregates testing equipment has therefore been designed to help you determine a wide range of factors. These include: particle size, shape and texture; relative, bulk and compacted densities; soundness and resistance to chemical attack; and mechanical properties.

42 Aggregates - Sampling and Preparation of Aggregates

Sampling and Preparation of Aggregates

Sampling and preparation of aggregates and fillers is necessary for a variety of reasons including research, design and quality control. The main aim of sampling is to obtain a sample representative of the average quality. Sampling techniques and procedures are described in various Standards including BS 812:Part 101 and 102 and ASTM D75. Individual items of equipment necessary for sampling and preparation are described in the Soils Section of the catalogue.

Drying and WeighingEN 932-2

Most test techniques involve the use of drying ovens and balances. A comprehensive range of equipment is described in the Laboratory Equipment Section of the catalogue.

Moisture Content

The moisture content of aggregate is of importance e.g. when batching concrete or when compacting unbound materials to achieve a specified density. Accurate means of determining moisture content are specified in various Standards and include methods suitable for use in the laboratory or on the construction site. Individual items of equipment necessary for determining moisture content are described in the Soils Section and the Laboratory Equipment Section of the catalogue.

Particle Size and Shape

Among many of the applications to which aggregate lends itself is its use in economical concrete mixes, impervious, durable asphalts, macadams and road bases. Particle size, shape and texture can have considerable effects on various design properties and are generally specified within certain limits. Rounded aggregate can lead to instability in a bituminous mixture yet be ideal as a concrete aggregate where good workability of the mix is essential for placing and compaction.

Determination of Particle Size EN933-1, BS 812; ASTM C136

A comprehensive range of sieves, sieve shakers and ancillary equipment will be found in the Laboratory Equipment Section of the catalogue. The range of sieves offered includes ISO 3310, BS 410 and ASTM E11 mesh sizes and frames.

Determination of Sand Equivalent Value ASTM D2419; AASHTO T176

The test is used to determine the relative proportions of clay-like or plastic fines and dusts in aggregate used for construction purposes.

For Sand Equivalent Apparatus see Section 24.

Sample ReductionRiffling or quartering are the two methods most often used to reduce a bulk sample to a representative size suitable for testing.

A Riffling, normally used for reducing material which is in a surface dry condition.

B Quartering can be used to reduce damp material down to a quantity which can be further prepared, e.g. by drying and then riffling.

42 Aggregates - Density, Voids and Bulking

Density, Voids and Bulking

As with any porous material, the value obtained for the particle density of an aggregate will depend on the method of test and apparatus used. Different particle sizes within a sample often have different particle densities. The term particle density expressed in Mg/m3 is numerically equal to the specific gravity. Various methods, depending upon the type and size of material to be tested, are specified in Standards for testing aggregate.

The main engineering use of bituminous materials is for road construction, with the material consisting primarily of two ingredients: aggregate and binder.

The term Asphalt is simply one of two generic names used to classify or describe bituminous mixtures; the other being Macadam. In the USA the term Asphalt denotes what in the UK is known as Bitumen.

Within these two broad groups lie an almost infinite number of mixtures which can be specified to suit particular engineering requirements. Our latest testing equipment has therefore been developed to enable construction engineers and laboratory staff to carry out a wide range of industry standard tests quickly, simply and reliably.

Our range of manual and automatic equipment allows you to determine properties that include optimum binder content, aggregate grading and void content, using traditional methods such as the Marshall test.

Mixing and Temperature

The density of Marshall specimens has a direct effect on stability and flow therefore the correct moulding and compaction of laboratory specimens is essential if economical design mixes are to be produced.

Efficient mixing, temperature and compaction control are closely related. Poor coating of the aggregate due to low temperatures during the mixing process will have a major effect on subsequent test results.

Electronic Instrumentation

u Peak load and the corresponding flowu Windows® download software supplied u User-selectable SI, Metric and Imperial Units u ECU features large character LCD display

A limitation of using conventional dial gauges in the Marshall test is the difficulty of accurately synchronising the measurement of flow with that of peak load reading.

To overcome this limitation the Marshall Test 50 load frame can easily be fitted with optional electronic load and flow measurement transducers connected to EL27-1200/09 (E)lectronic (C)ontrol (U)nit for simpler test operation and data recording.

At the end of a test the ECU will automatically hold the maximum load and flow readings enabling test data to be downloaded to a PC using the Windows® software supplied as standard with ECU.

Analysis and reporting can then be easily created in MS Excel or equivalent software.

The ECU can be programmed to automatically stop the load frame should transducer limits be exceeded, protecting test accessories and load frame drive system.

The above combination results in a powerful package to satisfy modern day laboratory Marshall testing requirements for accuracy and reliability.

Rock Mechanics

70 Triaxial and Permeability 77 Strength

Rock mechanics is the theoretical and applied science of the mechanical behaviour of rock; in particular the response of rock to changes in stress distribution, both below and adjacent to a structure or excavation.

Carrying out complex and expensive in-situ tests to determine rock engineering parameters is generally uneconomical in all but the largest construction projects. By comparison, laboratory testing, combined with simple yet efficient field test equipment, offers an effective and reliable alternative.

Our range of rock testing equipment has therefore been developed to help you identify, prepare and accurately and reliably test rock samples using industry standard testing techniques.

Permeability of Rock

Investigating the permeability or flow of water through rock subjected to high confining pressures is often necessary. The capacity of a rock mass at depth to transmit or yield water is of particular importance when designing deep structures such as tunnels.

Permeability end caps used with ELE-Hoek Cells and constant pressure systems are a cost-effective solution suited to investigating the permeability of rock at high confining pressures in the laboratory.

To collect and measure the water which permeates through the rock specimen, a suitable burette such as EL25-4540 is recommended. Each permeability end cap incorporates a tubing connector which accepts standard 6 mm tubing, EL26-1926, used to connect the cell to the pressure system and burette.

Sieve Shaker

Hand sieving of a large number of samples can often be tedious and sometimes lead to inaccuracy of results. The following machine provides a wide choice of options for the busy laboratory.

ELE Sieve ShakerEN 932-5

The ELE sieve shaker is powered by an electromagnetic drive that has no rotating parts to wear making it maintenance free and extremely quiet in operation.

The unit features a triple Vertical-Lateral-Rotary vibrating action that moves the sample over the sieve producing faster more efficient sieving, while the rapid vertical movements also help keep the apertures from blinding.

The shaker is ideal for laboratory or on site use. It is robust, compact and sufficiently lightweight to be portable. The separate digital microprocessor controlled console unit incorporates a keypad for setting the sieving program and is isolated from any effects of vibration from the shaker.

As standard the shaker includes, timer 0-999 minutes, adjustable vibration intensity and adjustable intermittent or continuous operation.

The unit accepts up to ten 200 mm or 8 inch, full height, diameter sieves and lid and receiver, or up to six 300 mm or 12 inch diameter sieves and lid and receiver.
