Calculate aggregate crushing value. the ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: aggregate crushing value = w b w a 100. where, w a is weight of surface-dry.
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.
Calculation of aggregate crushing value: aggregate crushing value can be found by the following formula, “aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 2.36 mm is sieve divided by weight of aggregate sample taken for test” aggregate crushing value = (w3 / w) or w3 / (w2 –.
