If you want to learn about our products , please call or write mail consultation.

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushingunder 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 determinedinstead
