Fineness of fine aggregate is related to term fineness modulus; most commonly sand. Fineness modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete. This can be defined as value that is derived by following expression:

How to Assess the Quality of Fine Aggregate at Site? ... As per IS 1542: 1992 – clause 5.2, the fineness modulus of sand shall be not less than 1.4 in case of crushed stone sands and crushed gravel sand and not less than 1.5 in case of naturally occurring sands. Lower FM indicates fine sand and higher FM indicates courser sand.

Obviously, it is used for plastering work. The fineness modulus should not be more than 1.5 and silt content should not be more than 4% in this type of sand. Concrete Sand. For the concreting purpose, we generally use coarse sand. The fineness modulus of this sand should be 2.5 to 3.5 and it should not contain more than 4% silt. Based on Their ...

The fineness of the sand plays an important role in the finishability of the concrete mix, and even small changes in fineness can affect finishing. The fineness modulus is a single parameter that describes the grading curve and can be useful in checking the uniformity of grading.
