Aggregate Crushing Value Test Procedure

The crushed aggregate sample which is finer than mm is separated and expressed as a percentage of the original weight taken in the mould The percentage of weight passed through the IS sieve is known as Aggregate crushing 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
