Values of Fineness Modulus of Sand Fineness modulus of fine aggregate varies from 2.0 to 3.5mm. Fine aggregate having fineness modulus more than 3.2 should not considered as fine aggregate. Various values of fineness modulus for different sands are detailed below.

How to calculate Fineness Modulus. Procure to determine Fineness Modulus. Sieve the aggregate using the appropriate sieves (80 mm, 40 mm, 20 mm, 10 mm, 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron & 150 micron) Note down the weight of aggregate retained on each sieve. Calculate the cumulative weight of aggregate retained on each sieve.

The same value of fineness modulus may therefore be obtained from several different particle size distributions. In general,however,a smaller value indicates a fineraggregate. Fine aggregates range from a FM of 2.00 to 4.00, and coarse aggregates smaller than 38.1 mm range from 6.50 to 8.00.

An example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate, the table indicates that 0.71m3 of coarse aggregate, on a dry-rodded basis, may be used in each cubic meter of concrete. The required dry mass is, therefore, 0.71 x 1600 = 1,136kg."

Fineness Modulus of Fine Aggregate: The sand fineness module (fine aggregate) is an index number describing the mean size of sand particles. By doing sieve analysis with normal sieves, it is measured.. The accumulated percentage kept on each sieve is applied and the sum of the fine aggregate is subdivided by 100. To find the fine aggregate fineness modulus, we require 4.75mm, 2.36mm, …

The aim of this work was to evaluate the relationship between the basic properties of different fine aggregates, such as specific gravity, fineness modulus and bulking, and then relate them to the compressive strength, water absorption and sorptivity. This would facilitate the engineer in choosing the fine aggregate based on its basic properties.

When fineness modulus is indicative of the weighted average particle size of the sample to be in two successive sieves from the lowest sieve. For instance, a fineness modulus of 3 represents the third sieve from 150µm. The same fineness modulus can represent a number of different size distributions and grading curves.
