Jul 18, 2021 · Crushing Value Test of Aggregates – Importance, Procedure, and Standard limits. The aggregate crushing value test on coarse aggregates gives a relative measure of an aggregate under a gradually applied compressive load. It is a numerical index of the strength of the aggregates. This test is helpful in the construction of roads and pavements.

What is the importance of finding bulk density of coarse aggregate and percentage of voids. Bulk density of coarse aggregate and their specific gravity along with bulk density of cement fine aggregate and coarse aggregate and specific gravity of coarse aggregate and cement is quite helpful in finding in design of mix concrete like M20,M25,M30 and so on .

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than mm (retained on a No. 4 sieve), while fine aggregate is less than mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
