The aggregate crushing value (ACV) of an aggregate is the mass of material expressed as a percentage of the test sample which is crushed finer than a 2 36 mm sieve when a sample of aggregate passing the 13 2 mm and retained on the 9 50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN 2 APPARATUS 2 1 An
