    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

  • Aggregate Crushing Value Test  Significance  Test
    Aggregate Crushing Value Test Significance Test

    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
