6) Release the load and remove the material from the cylinder. 7) Sieve the material with 2.36mm IS sieve, care being taken to avoid loss of fines. 8) Weigh the fraction passing through the IS sieve. Calculation: After 2.36 (8) sieves retained = 1990 gram. 2500−1990 ACV = × 100 2500 f = 20.4 % Result: Aggregate crushing value = 20.4% Result
