The test aims at looking for the forces required to produce 10% of fine values ( weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.

Aggregate Crushing Value Test Procedure And Result

Sampling for Aggregate Crushing Value Test: For the Aggregate crushing value test, an aggregate sample passing through mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mould about kg of a sample of aggregate is sufficient.
