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 figure of aggregate crushing value test - rodiziogrillbe sieve size aggregate crushing value lesfrenchi Figure 33: Sieve size 236mm Compression testing machine which capable of applying force of 400kN Figure 34 Crushing machine So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate
