Crushing Value Test (IS 2386 (Part IV)) The material for the test should consist of aggregate passing 12.5 mm sieve and retained on 10 mm sieve. For other sizes, the materials are separated on the appropriate sieves given in Table . Table 10 Details of Aggregate Crushing Test for Non standard Sizes of Aggregate.If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.
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.
