The fineness modulus is abbreviated as FM. FM of sand (fine aggregate ASTM standard) is an index number that represents the average size of the grain of sand. It is calculated by performing a Sieve Analysis with ASTM standard sieves 3″, 1/2″, 3/4″, 3/8″, No. 4, No. 16, No. 30, No. 50, and No. 100 and dividing the sum of the cumulative

Fineness Modulus of Cement. The fineness modulus of cement is an empirical value determined by adding up the percentage of aggregate retained on each sieve in a particular sequence and then dividing the total by 100. It is possible to calculate the percentage of cement whose grain sizes are greater than the required mesh size.
