The Fineness Modulus should be between 2.3 and 3.1. FM is an index of the fineness of an aggregate-the higher the FM the coarser the aggregate. Different aggregate grading may have the same FM. FM of fine aggregate is useful in estimating proportions of fine and coarse aggregates in concrete mixtures.

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 ...

The fineness modulus of coarse aggregates typically ranges from 5 to 8. A lower fineness modulus indicates a coarser aggregate, while a higher value indicates a finer aggregate. As per the standard guidelines, a fineness modulus of 2.2-2.6 is considered to be fine, 2.6-2.9 medium, and 2.9-3.2 coarse.
