Calculation ofAggregate Crushing Value. Thecrushing valueof aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the driedaggregatesample. At least three samples should be tested from the same batch and averagevalueto get accurate results. Thecrushing valueofaggregate

crushing value apparatus (acv), aggregates testing
The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available:150(standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure. Cylinder, plunger and base plate are made from special alloy steel, hardened to 650 HV (57,8 HRC), and protected …
