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 ...

To determine the fineness modulus of fine aggregate, sieve diameters of 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm, and 0.15mm are required. The fineness modulus of finer aggregate is smaller than that of coarse aggregate.

The fineness modulus of sand is crucial in determining the workability and strength of concrete used in construction. A higher fineness modulus indicates a coarser sand, which may result in a less workable concrete mix. On the other hand, a lower fineness modulus indicates finer sand, which may lead to a more workable but weaker …

Fineness modulus of sand is a index number, which represent the mean size of particle in sand. Fineness modulus is found by performing the sieve analysis. The formula to find out the fineness modulus is, all the sum of percentage cumulative retention of each sieve divided by 100, provides values of Fineness modulus. Fineness modulus =.
