Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
Aggregate Crushing Value Test Learning Technology
The Aggregate Crushing Value Test is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load.
