Apr 26, 2018· The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the totalaggregates (Wa-We)W2=Weigh of aggregatespassing through 2.36mm IS sieve. Aggregate crushing value= (W2 / W1) × 100
[email protected]Calculation of Aggregate Crushing Value. The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place.Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve. W1-W=Weight of surface dry sample.
