Determination of aggregate crushing test

Apr 06, 2021

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. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve

    A loading crushing test of recycled mixed coarse aggregates in the same particle diameter range is carried out, and the crushed coarse aggregates are screened, manually sorted, and weighed to study the crushing characteristics of recycled mixed coarse aggregates. The results show that the effect of “reinforcing the strong and discarding the weak” exists between two types of recycled
