The dividing line between fine and coarse aggregate is the 3/8inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100 (see Table 1).

The index number, which describes the relative sizes of coarse and fine aggregates, is called as fineness modulus (FM). Fineness modulus is determined separately by sieving coarse and fine aggregates through the following set of sieve. IS sieves for coarse aggregates are 80 mm, 40 mm, 20 mm, 10 mm and mm.
