METHOD B1 THE DETERMINATION OF THE AGGREGATE Aggregate Crushing Value Test Procedure and Result
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 21 An For this reason assessment of strength of the aggregate is made by using a sample of bulk aggregate in a standardized manner This testing method is known as an aggregate crushing value test Aggregate crushing value provides the resistance of an aggregate sample to crushing under gradually applied compressive load
