#### AGGREGATE CRUSHING VALUE

AGGREGATE CRUSHING VALUE 1.Objective 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.

Workability is another factor for aggregate selection. Increasing the size of aggregates, elongated and angular shapes reduce workability while more rounded and smaller aggregates are easier to work with. The strength of a concrete mix largely depends on the strength properties of aggregate and its chemical content.
