Aggregate Crushing Compressive

Aggregate crushing value ive 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
