PREFORMED FILLERS FOR EXPANSION JOINT IN CONCRETE PAVEMENTS ANDSTRUCTURES (NON EXTRUDING AND RESILIENT TYPE) SPECIFICATION

PART 3 (TO IS 1838) POLYMER BASED FILLERS

-------------------------------------------------------------------------------------------------------------Building Construction Practices Last Date for Receipt of Including Painting, Varnish ing Comments is 31 December 2009 and Allied Finishes Sectional Committee, CED 13-------------------------------------------------------------------------------------------------------------FOREWORD

(Formal clauses of the foreword will be added later ) J oints are required in concrete pavements, roads, runways, floor and roof slabs inbuildings to relieve stresses developed due to temperature shrinkage, creep, relaxation,vibration, etc. To provide an even surface these joints must be filled and at the same timethe materials used for filling should permit expansion and contraction of the concretemember. The joint filler is a strip of compressible material used to form and fill theexpansion joints in structures. The chief function of the joint filler is to permit the joint toexpand without developing stresses. J oint filler are produced from a variety of materialssuch as bitumen impregnated fibre, cork strips, sponge or synthetic rubber, expandedplastics, epoxy, coconut pith and CNSL resin.

To make the joints effective it is also necessary to prevent the ingress of water or gritdown the joint. This is achieved by using a sealing compound over the joint filler. Therequirement for sealing compounds and methods of installation of joints has been coveredseparately IS 1834, IS 3414, IS 6509, IS 11433 (Part 1) and IS 12118.

The following are the existing Indian Standards on expansion joint fillers:

IS 1838 Specification for preformed fillers for expansion joint inconcrete pavement and structures(non extruding and resilient type):

(Part 1):1983 Part 1 Bitumen impregnated fibre (first revision)

(Part 2):1984 Part 2 CNSL Aldehyde resin and coconut pith This standard ( proposed Part 3 to IS 1838) has been prepared to cover the requirementsfor polymer based filler type of expansion joint fillers.

For the purpose of deciding whether a particular requirement of this standard is compliedwith the final value, observed or calculated, expressing the results of a test or analysis,shall be rounded off in accordance with IS 2:1960 Rules for rounding off numerical values.

The number of significant places retained in the rounded off value should be the same asthat of the specified value in this standard.

Draft I ndian Standard

PREFORMED FILLERS FOR EXPANSION JOINT IN CONCRETE PAVEMENT ANDSTRUCTURES (NON-EXTRUDING AND RESILIENT TYPE) SPECIFICATION

PART 3 (TO IS 1838) POLYMER BASED FILLERS

1. SCOPE

1.1 This standard specifies the requirements for polymer based fillers for expansion joints.

1.1.1 The fillers may be used for filling expansion joints such as in buildings,concrete pavements and other structures.

2. REFERENCES

The standards listed in Annex A contain provisions which through reference in thistext, constitute provisions of this standard. At the time of publication, the editionsindicated were valid. All standards are subject to revision and parties to agreementbased on this standard are encouraged to investigate the possibility of applying themost recent editions of the standards indicated in Annex A.

3. MATERIAL

3.1 The material used shall be cross-linked polymers that are non-absorbent, non-staining, non-deteriorating, closed-cell and compressible in nature.

4. MANUFACTURE

4.1 The materials shall be suitably polymerized to obtain fillers for appropriate useconforming to the specifications laid down in this standard.

5. DIMENSIONS AND TOLERANCES

5.1 Dimensions Typical dimensions of the individual filler member are as follows:

Length 1 800 mm, 2 200 mmWidth 900 mm, 1 100 mm Thickness 8 mm (min)

50 mm (max)

Alternatively, the dimensions of the performed strips shall be mutually agreedbetween the purchaser and the manufacturer. For dimensional measurements, areference may be made to IS 10566.

5.2 Tolerance The tolerance on the average dimensions shall be as given below:

On length + 5 mmOn width + 3 mmOn thickness +1.5 mm

6. PHYSICAL REQUIREMENTS

6.1 The physical requirement of the fillers shall conform to col 3 of table 1 when tested inaccordance with the method specified in IS 10566.

7. TYPICAL LAYING PROCEDURE

7.1 Laying Procedure

The filler material may also be used as shuttering on one side the expansion joint byabutting with the already cast member. To hold the two free sides of shuttering, suitableMS bolts both threaded sides may be used at every regular interval (say 1 m) and securedwith concrete using appropriate nuts. These bolts shall be taken out later and the holegrouted with suitable cement mortar. ( see Fig. 1)

Fig 1. Typical layout of use of the fill er as shuttering to column member

In an expansion/movement joint the filler member is to be fixed in position to thesubstrate using double sided adhesive tape/other synthetic adhesives.

When forming expansion joint with the filler member in in-situ concrete, joint sealingslots is to be formed in the following manner:

The filler is used as one side of the shuttering. Cut off a strip of the filler equal toD. Further; cut the strip along the joint length into two.

The depth of top strip may be (1.25 W or W + 5mm whichever is less) +(W/2 or15mm whichever is less) and the depth of bottom strip be (D - top strip)

Where,

D = slot depth, in mmW = slot width, in mm

Pin the top strip back on to the bottom strip using nails at two-inch intervals.Ensure that the slot is clean and dry. Install a strip of filler material on top of thefiller flush with finished surface using either a tape / synthetic rubber basedadhesive [see fig 2 (steps 1-4)].
