Aggregate Crushing Value (ACV) Civil Engineering . 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.
So this aggregate was not strong. 4 CONCLUSION The ACV value is more than 45% for aggregate used for concrete for non- wearing surface and less than 25% for wearing surface like runways and roadways. The higher the aggregate crushing value, the lower the resistance to crushing under the gradually applied compressive load. 5 REFERENCES
