Effect of Coarse Aggregate Size Variation on Compressive
Aggregate Crushing Test. The crushing strength of aggregate was calculated by adopting the procedures as standardized in IS:2386 part IV. In a cylindrical measure of 11.5 cm diameter & 18 cm height the dry aggregate passing through 12.5mm size sieve & retained in 10mm size sieve was filled in three layers.

Application of Aggregate Crushing Test: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low. Thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types
