Scope: 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.

The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm. The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC - 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.
