Aggregate Crushing Value Of Aggregates With Cement
BS 812 part 110 describes a method to determine the aggregate crushing value ACV which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. An aggregate specimen is compacted into a steel cylinder fitted with a no-friction plunger.
