The Fineness Modulus is used in US practice and is a measure of the grading of fine aggregates. It can be calculated from a sieve analysis by adding the cumulative percentages of fine aggregates retained on the following sieve sizes 0.15mm 0.30mm 0.60mm 1.18mm 2.36mm and 4.75m. This value is then divided by 100 to give the fineness modulus.
