Jul 23,  · The aggregate crushing value (ACV% = W2/W1 x 100). The acceptance criteria for aggregates as in IS 383 specification for crushing test is given below: For wearing surfaces the (ACV) value should be lower than or equal to 30 percent. For concrete other than wearing surfaces, the (ACV) value should be lower than or equal to 45 percent.

Apr 26,  · Calculation of aggregate crushing value. 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 total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve. Aggregate crushing value=( W2 / W1 )
