### Fineness Modulus - an overview | ScienceDirect Topics

3.4.3 Fineness Modulus. The significance of fineness modulus (FM) is in specifying the proportions of fine and coarse aggregates when designing concrete mixes. The higher the value of FM, the coarser the aggregate. Generally, a lower FM results in more paste, making the concrete easier to finish.

A greater proportion of coarse aggregate (i.e., a decrease in S/A ratio) improved the mechanical properties by 10% compared to the control specimens (S/A ratio: 52%) at 56 days. A higher S/A ratio was shown to improve bonding capacity by enhancing the roughness of the particles and thereby increasing adhesion strength.

crushing. Coarse aggregates smaller than 20 mm were suggested to be eliminated as they may interrupt the grout flow. Neville proposed the use of coarse aggregates of sizes smaller than 38 mm, with the aggregates being gap-graded and of multiple sizes [13]. Later, the minimum size of coarse aggregates of 10 mm was suggested by Orchard [14].

Bulking of Sand – If the moisture is present in the sand, then it makes the sand look bulkier, which could result in inadequate sand proportion in the concrete ratio. If we need to add 1m 3 sand in the concrete mix ratio, we take 1.3 m 3 (30% more). The reason for that is the moisture content present in the sand makes it a little bulkier.
