ContactThe aggregate crushing value formula is given below, Aggregate crushing value = (W3 / W) or W3 / (W2 W1) W1 = Empty weight of cylindrical Measure. W2 = Weight of Aggregate with Cylindrical Measure W = W2 –W1 = Weight of Aggregate Sample W3 = Weight of crushed aggregate sample passed through 2.36 mm IS Sieve.

ContactApr 08, 2017The aggregate crushing value provides a subjective measure of the resistance of the aggregate crushing in the pressure of the progressively smeared compressive load. When the aggregate crushing value is 30 or greater the outcome can be irregular and in those kind of circumstances the ten percent fines value has to be assessed in its place.

ContactAGGREGATE 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.
