The aggregate impact value indicates a relative measure of the resistance of aggregate to a sudden shock or an impact, which in some aggregates differs from its resistance to a slow compressive load The method of test covers the procedure for determining the aggregate impact value of coarse 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 The sample aggregate should be free from moisture

The ratio of aggregate which passes through the sieve to the total weight of sample in each test in terms of percentage is the impact value of aggregate Now we compute the impact value using these two test using the formula below Aggregate impact value = W2/ W1 *100 where, W2 – Weight of aggregate which passes through the IS sieve 236mm

The aggregate impact value test is an important test of aggregates It is done to obtain the resistance and impact of aggregates (stones) In this test a machine is used, which is called impact
