Aggregate Crushing Value Test - Cement Concrete

The aggregates passing through a 12.5 mm sieve and retained on a 10.0 mm sieve comprise the test material. Take about 3.25 kg of this material. Aggregates should be poured to fill about just more than 1/3 rd depth of the measuring cylinder. The material is compacted by giving 25 gentle blows with the rounded end of the tamping rod.

To find the volume needed, determine the amount of area to be covered by gravel as well as the desired depth of the gravel. The ideal depth of gravel varies depending on the application, but a minimum of 2-4 inches of gravel is a workable baseline. Multiplying the area to be covered by the desired depth yields the volume of gravel you will need.
