The crushed aggregate is removed and sieved on a 2.36 mm I.S. sieve. The material passing through this sieve is collected and weighed. The aggregate crushing value is obtained by the following expression: A g g r e g a t e c r u s h i n g v a l u e = W 1 W 2 × 100. Where W2 = Total weight of the dry sample.
