determination of aggregate crushing value

May 05, 2010· Calculation of Aggregate Crushing Value. The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place. Aggregate crushing value= (W2 x 100) / (W1-W)

    The test aims at looking for the forces required to produce 10% of finevalues(i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar toAggregate CrushingTest in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is theaggregate crushing value.
