Aggregate Impact Value Test Procedure IS 2386 Part 4-1963

Procedure of Aggregate Impact Value Test:- Take test samples of aggregates passing through 12.5 mm IS sieve and retained on 10 mm IS sieve. Dry theme in an oven for 4 hours at a temperature of 100 C to 110 C and then cool at room temperature.

Aggregate Impact Value - Civil Engineering

Procedure to determine Aggregate Impact Value i The cup of the impact testing machine should be fixed firmly in position on the base of the machine and the whole of the test sample placed in it and compacted by 25 strokes of the tamping rod.

Aggregate Impact value test procedure Civil4M

AGGREGATE IMPACT VALUE TEST AIM: To find Impact value of the given aggregate sample. APPARATUS The apparatus consists of an impact-testing machine a cylindrical measure tamping rod IS sieve balance tamping rod and oven. PROCEDURE The test sample consists of aggregates passing 12.5 mm sieve and retained on 10 mm sieve and dried in an oven for four hours at a temperature 1000 C to 1100 C

Determination of Aggregate Impact Value - Impact Test on Aggregates

The aggregate impact value is a measure of resistance to sudden impact or shock which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110 C for a period of 4 hours and cooled.

Impact Test on Aggregates - GharPedia

The following procedure is applied to find out the impact value of aggregate: Aggregates for the test sample can be decided by passing it through 12.5 mm sieve and retained on 10 mm sieve. The sieved aggregates should be dried in an oven and then filled in a cylindrical steel cup and tamped with 25 strokes by temping rod.

Aggregate Impact value Test Apparatus Procedure and uses pavement materials - Cement

Procedure of Aggregate Impact value test. The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the material through 12.5mm and 10.0 mm IS sieves. The aggregates passing through 12.5 mm sieve comprises the test material.

Aggregate Impact Value Test - Procedure and Uses - Civil Planets

This test is performed to ensure the aggregate toughness which is used in road construction to work as a base layer sub-base layer. How do you calculate the aggregate impact value? The impact value is measured in the ratio between the sieved aggregate of 10mm and 2.36mm aggregates. The aggregate impact value test will be conducted as per the Indian Standard Code IS code 2386 Part 4. Let’s start with the experiment to understand the concept better. Precautions to be taken

Impact Test Of Aggregate Lab Test Procedure Recommended Values For Impact Test

The procedure of the impact value test includes the following series of steps: 1. The aggregate samples of size 10mm to 12.5mm passing through 12.5mm sieve and retained on 10mm sieve are first taken and oven-dried at a temperature ranging from 100 degree Celsius to 110 degree Celsius for about four hours.

Aggregate Impact Value Test Procedure Result and Standards

Aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm weight W2 by the total weight of the sample weight W1 W2 . Aggregate Impact Value = W2/ W1 W2 * 100 = 80 gm / 300 gm = 26.67 Impact Value Where W1= Weight of the fraction passing through 2.36 mm IS sieve. 220 gm

Aggregate impact value test- step by Step Procedure with Report

Significance of impact test. The procedure of determining aggregate impact value is according to IS 2386. More will the impact value more will be the strength of aggregate. The elongated and flaky aggregate has low strength as it has a higher surface area and gets more stress on it. Different impact value of aggregate should be used for different types of pavement given below. Recommended aggregate impact value
