## Types of Testing for Aggregates Structural Guide

TESTING OF AGGREGATE CRUSHING VALUE Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased It is tested in accordance with BS 812:110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing The allowable range is 17 41the 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 140 mm test sieve and retained on a 100 mm test sieve For other size fractions, there is another recommended methodMethods for determination of aggregate crushing valueThe crushed aggregate sample which is finer than 236 mm is separated and expressed as a percentage of the original weight taken in the mould The percentage of weight passed through the 236m IS sieve is known as Aggregate crushing value In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determinedAggregate Crushing Value Test Procedure And Result
