Strength of the aggregates simply means compressive or crushing strength of the aggregate. It is represented by aggregate crushing value. ACV is the quantified resistance provided by aggregates to the progressively applied compressive/crushing loads. This is generally determined for coarse aggregates.

This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%.
