Read MoreAggregate Crushing Value ACV The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.
