Method for aggregates passing a 14.0 mm test sieve and returned on a 10.0 mm test sieve. Also describes a method for other size fractions.

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 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, a recommended method is described in appendix A.

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 fines value described in BS 812-111 is applicable.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
