Aggregate Crushing Value Test Determine Aggregate
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditionsThe crushed aggregate sample which is finer than 236 mm is separated and expressed as a percentage of the original weight taken in the mould The percentage of weight passed through the 236m 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 determinedAggregate Crushing Value Test Procedure And Result
