Objective For determination of the aggregate crushing value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm. IS sieve. Reference Standard IS: 2386 (Part IV)-1963 Methods of test for aggregate for concrete Part IV Mechanical Properties.
Calculations: Aggregate Crushing Value = (B/A) * 100 % * The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. * Aggregate crushing value < 45% for aggregates used for concrete for non wearing surfaces and <25% for wearing surfaces like runways and roadways.
