Dec 16, 2020 The aggregate crushing value of the coarse aggregates used for cement concrete pavement at surface should not exceed 30 and aggregates used for concrete other than for wearing surfaces, shall not exceed 45 as specified by Indian Standard (IS) and Indian Road Congress (IRC).Used to determine the crushing value for the aggregate particles. Contains the standard Aggregate Crushing Value pieces. The cylinder supplied with the set is made of a heavy duty steel to resist the impacts during the test. Includes a plunger tamping rod and a base plate.
Standard Specification and Code of Practice for the aggregate impaet value of coarse aggregates. limits of aggregate impact value specified for Aggregate Impact Value This test is done to determine the aggregate impact value of coarse aggregates as per IS 2386 (Part IV) – 1963. . for non wearing surface its max. limit is 45 .The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.
Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa We) W2= Weigh of aggregates passing through 2.36mm IS sieve.May 22, 2020 The aggregate crushing value= B A 100 . Where, B is weight of fraction passing 2.36mm sieve A is weight of surface dry sample taken in mould. Note. The aggregate crushing value should not be than 45 for aggregate used for concrete other than the wearing surfaces. 30 for concrete used the surfaces such as runway, roads and air field.
