Crushing Test On Aggregates

BS 812 110:1990 aggregates. Methods for

The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, a recommended method is described in an appendix to this standard. The method is not suitable for testing aggregates with an aggregate crushing value higher than 30, and in such cases the method for ten per cent

METHOD B1 THE DETERMINATION OF THE AGGREGATE

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
