Aggregate | Classification & Test on Aggregate

 · This test gives the Aggregate Impact Value (AIV), which is an index of the resistance of. aggregate to sudden shock or impact. The apparatus used for this test is called Impact Testing Machine. A sample of aggregates in surface dry condition, which pass through 12.5 mm sieve and are retained on 10 mm sieve are taken for this test (W1).

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
