The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing machine. The material is filled in 3 layers where each layer is .The aggregate impact value is expressed as percentage of fines formed in terms of the total weight of sample. Let the original weight of the oven dry sample be W 1 g and the weight of the fraction passing 2.36 mm IS sieve be W 3 g. Aggregate Impact value = 100 W 3 W 1 Result: Aggregate impact value of specimen ----- If the aggregates are weak, the stability of the concrete structure is adversely affected. The strength of coarse aggregates is assessed by Aggregate Impact Value test. The aggregate impact value provides a relative measure of resistance to sudden shock or impact. APPARATUS 1.
