Materials [8]. The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value tests are commonly carried out for normal weight aggregates. In its place, “10% fines value” and “impact value” can be conducted for lightweight aggregates.
