This Part of BS 812 describes a method for the determination of the aggregate crushing value ACV which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load The method is applicable to aggregates passing a 140 mm test sieve and retained on a 100 mm test sieve
Get Price
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 236 mm sieve when a sample of aggregate passing the 132 mm and retained on the 950 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN 2 APPARATUS 21 An
