The Aggregate impact test is used to determine the aggregate impact value(AIV), which provides a relative measure of the resistance of a coarse aggregate to sudden shock or impact. Lower Aggregate Impact values indicate aggregates that are stronger or more impact resistant.

What is the aggregate impact value test? 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.
