Aggregate Crushing Value (ACV) test indicates the resistance to crushing under gradually applied crushing load. It is measured as percentage of aggregates passing through 2.36 mm IS sieve after specimen subjected to a compressive load of 40 tonne at the rate 4 tonne per minute and to the weight of aggregates taken.
The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
