Aggregate Testing | 7 Test On Aggregates | Coarse
2. Crushing Value Test of Aggreagte. What Is Crushing Value? Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load.. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.

Aggregate Crushing Value Test -Determine Aggregate
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.
