Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. 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 fineness modulus.

One of the prime indicators of superior sand quality is fineness of grain size. Grain fineness is a measure of the amount of sand passing through certain screens. Grain size and shape affect both the escape of hot gases from the molten metal poured into the mold and surface texture of the casting. The finer the sand used the smoother the finish.
