Aggregate Crushing Value Calculator, Test on course and Fine Aggregate
Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surface-dry sample; W B is weight of fraction passing the appropriate sieve; Reporting of Results. The mean of the two results shall be reported to the nearest whole number as the 'aggregate crushing value' of the size of material tested.

Determination the Crushing Value of Aggregate test
The Crushing Value test measures the ability of an aggregate to resist crushing under a compressive load. It is a measure of the strength and toughness of the aggregate. In this test, a standard crushing load is applied to a prepared aggregate sample, and the percentage of fines generated after the specified amount of crushing is determined.
