The sample is then sieved on 2.36 mm IS sieve until no further significant amount passes in one minute. The fraction passing the sieve is weighed to nearest accuracy of 0.1g (W2) The crushed aggregates (W2) is expressed as of the total weight of sample (W1), which is the crushing value of the aggregate. Aggregate crushing value = (W1 W2) 100.
