Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Apr 29, 2017 As per most codes of practice, concrete strength is expressed as the characteristic strength, i.e. not more than 5% of test samples will fall below this value of strength. In the Indian Code IS: 456, strength is expressed as the characteristic str...

Jun 08, 2020 The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred.
