IntroductionDuring ground shaking there can be

Loss of grip on beam bars. Cracking and crushing of concrete.

Lateral loading on frame structure:

Sap 2000

Sap 2000

Tests to be performed before calculations

1. Sieve Analysis for sand and coarse aggregate2. Specific gravity of sand3. Bulk density of coarse aggregate

MIX DESIGN

SandTo find fineness modulus

Coarse aggregateTo find aggregate of size ¾"

Sieve Analysis

It refers to the degree of coarseness

lower value ----- finer sand (less porous concrete)higher value ----- coarser sand (more porous concrete)

Purpose:Used to find vol. of coarse agg in mix design of concrete

Fineness Modulus

Fineness Modulus = sum of cumulative % retained = 246.2 100 100

= 2.5

ResultsSieve no. Retained

#100 64 12.8 87.2 96

PURPOSE: It is done to find out coarse agg. of size ¾”

Procedure:Pass coarse agg of different sizes from ¾” sieve until we get

95% of agg retained on it.

SIEVE ANALYSIS FOR COARSE AGGREGATE

Purpose:Proportioning of cement, sand, crush and water

Required Strength -------- 2000Psi

Design Strength -------- 3000Psi

MIX DESIGNACI 211

Background Data:

Slump range ----------- 1-2in

Max size of coarse aggregate ----------- 3/4in

Specific gravitySand ----------- 2.32 Cement ----------- 3.15

Fineness Modulus ----------- 2.5

Bulk density of coarse aggregate ----------- 91.69 lb/ft3

Calculations: Step-1

Weight of water = 315 lb/yd3

Calculations: Step-2

Wt. of Cement = wt. of water = 463.24 lb/yd3

W/C ratio

Calculations: Step-3

Wt. of Coarse agg. = vol. of agg x bulk density = 0.65 x 91.69 lb/ft3 x 27 ft3/yd3

= 1609.15 lb/yd3

Calculations: Step-4

Wt. of fresh concrete = 3960 lb/yd3

Calculations: Step-5Wt. of sand = Wt. of concrete

– Wt. of water, cement and coarse agg.

= 1572.61 lb/yd3

Ratio by weight

1 : 3.4 : 3.5

Using developed proportions, mix a trial batch ofconcrete and perform tests for

1. Slump2. Compressive strength

Trial Batch

Purpose:

Consistency Workability

Workability A good mix design must be capable of being placed and compacted, with minimal

bleeding and segregation, and be finishable.

Consistency Consistency indicates amount of water used in the mix. Or it indicates the water cement ratio.

Slump Test

Segregation of aggregates

Porous Concrete

WATER CEMENT RATIOIt is the ratio of water and cement (by weight or by volume) used in the preparation of concrete.

Pouring of concrete Layers of 7.5 cm depth. Each layer is rammed 25 times. After few minutes mould is lifted. The extent by which the concrete drops is called the slump.
