Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm 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. The crushing value of aggregate (W2/W1) x 100. Lab Report Jan 25, 2021 Aggregate Crushing Value (ACV) IS 2386 2016 Method of Test for Aggregates for Concrete part IV Mechanical properties (Aggregate Crushing value) (The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS 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.

The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provider. a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregate possessing low Therefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test.
