AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.

Aggregate Crushing Value Test - Procedure And Result ...

The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined ...
