Apr 26, 2018· The aggregate crushing value is defined as theratio of the weight of fines passing through specified IS (here2.36mm sieve)to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2=Weighof aggregatespassing through 2.36mm IS sieve. Aggregate crushing value= (W2 / W1) × 100

The crushing value of aggregates is measured in the ratio between thecrushed 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

General description. 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, …

Aggregate Impact Values, (AIV’s), below 10 are regarded as strong, and AIV’s above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Aggregate Impact Value
