The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the IS sieve 236mm and the weight of the dried aggregate sample At least three samples should be tested from the same batch and average value to get accurate results The crushing value of aggregate W2W1 x 100

Calculation of Aggregate Crushing Value Aggregate crushing value can be found by the following formula “Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 236 mm IS Sieve divided by weight of aggregate sample taken for test” Aggregate crushing value W3 W or W3 W2 – W1

The ‘ aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions and the strength of the aggregate used in road
