Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate.

Sep 12, 2015Then crushed aggregates are then sieved through 2.36 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
