Get Priceconcept 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 material obtained when the test aggregates are subjected to a specified load under the aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed material obtained when the test sample is subjected to a specified load under standard conditions.the crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.m and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.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.
