The Fineness modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100.The sieve sizes are 0.15 mm, 0.3 mm, 0.6 mm, 1.18 mm, 2.36 mm, 4.75 mm, 9.5 mm, 19.0 mm, 38.1 mm and larger increasing in the ratio of 2:1.

The proportions between coarse and fine aggregates will change based on the unique characteristics of each aggregate, the placement method, and the finish desired. The dividing line between fine and coarse aggregate is the 3/8-inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate.

The procedure requires that a known amount of aggregate ... The calculation for moisture content (P) is as follows: P = 100 (W - D) D

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.
