Crushing Value Apparatus

The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of the resultant fines passing the specified IS sieve to the total weight of the sample expressed a s a percentage is defined as Aggregate Crushing Value. The apparatus is available in three size 75mm dia for 18” to ¼” size aggregate, 150mm dia for 38” to ¾” aggregate (standard) and 300mm dia for 1” to 2” aggregate.
