2009-4-17  Sand is a granular material made up of fine rock particles. Sand is a naturally occurring, finely divided rock, comprising particles or granules ranging in size from 0.0625 (or 1 ⁄ 16) to 2 millimeters. An individual particle in this range size is termed a sand grain.The next smaller size class in geology is silt: particles below 0.0625 mm down to 0.004 mm in size.

What is Fineness Modulus of Sand (Fine Aggregate)

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.
