الحصول على السعرCrushing value is defined as the ratio of finess passing a standard sieve produced by crushing under standard condition to the weight of coarse aggregate expressed as a percentage. Aggregate crushing values as determined by the IS code method shall not exceed 30 for aggregate to be used for making concrete for wearing surface such as roads and runways and 45 for uses other than wearing
الحصول على السعرThe crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregates.
الحصول على السعرSep 12, 2015· Then crushed aggregates are then sieved through mm sieve and weight of passing material (W2) is expressed as percentage of the weight of the total sample (W1) which is the aggregate crushing value. Aggregate crushing value = (W1/W2)*100. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates. Also Read: .
