Concept and significance of the Aggregate crushing value test. The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under

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.
