  • DETERMINATION OF AGGREGATE CRUSHING VALUE

    aggregate to crushing under a gradually applied compressive load Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum crushing value 3 APPARATUS The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of:The 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 | Crushing Value Of
