A relative measure of the resistance of aggregate due to the sudden shock or impact on it is called aggregate impact value. Based on the impact value, we can decide whether the coarse aggregate is suitable for construction or not. This test is performed to ensure the aggregate toughness, …
This testing method is known as an aggregate crushing value test. The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under a gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.
The procedure for conducting an Aggregate Impact Test (AIV) is as follows: Prepare the test sample by selecting aggregates sized between 10.0 mm and 12.5 mm. …
