Get PriceWhat is Aggregate Impact Value? The aggregate impact value indicates a relative measure of the resistance of an aggregate to a sudden shock or an impact, which differs from its resistance to a slow gradually increasing compressive load. Why to test Aggregate Impact Value? Toughness is the property of a material to resist impact.

Get Price2021-8-23 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.
