· The construction industry relies heavily on the sand. In construction, the fineness modulus of sand is an important parameter. It impacts the relative proportions in the mix, the workability, the economy, the porosity, and the strength of the concrete.

Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm.

The Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, dividing the sum by 100. Sieves sizes are: 150-μm (No. 100), 300-μm (No. 50), 600-μm (No 4.

The fineness modulus is the sum of the total percentages of a sample of aggregates retained on each of a specified series of sieves, and the sum divided by 100 [88]. The flakiness index is the percentage, by mass, of the particles whose least dimension is less than three-fifths of the mean dimension [121]. Table 4.
