Fineness modulus of sand is defined as the cumulative amounts of aggregate that remained on each of the sieve sizes ranging from 75 mm to 150 microns are added together and divided by 100. The fineness modulus is commonly used to determine the coarseness or fineness of an aggregate.
The fineness modulus cannot represent the particle size distribution, but it is useful for measuring slight variations in the aggregate from the same source, i.e., as a day to day check. Based on the practical experience, the fineness modulus of fine aggregate should be between 2 to 3.5 and of coarse aggregate between 3.5 to 8.
