What Is Fineness Modulus of Sand? 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.

Fineness Modulus (FM) is an empirical calculation used to support the optimisation of a concrete mix design. It is used to determine 'degree of uniformity of the grading'. This can create a relationship between grading and consistence and/or the amount of cement or water to fill the voids. An example would be that sand with a high FM will ...
