To Determine The Crushing Strength Of Concrete Block

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
