1. Fineness Modulus. It is one of the factors that influence concrete mix design since it controls the proportion of sand in concrete mixture. The overall fineness of sand is given by factor called fineness modulus, and it is found by sieve analysis based on ASTM C 33/ M33 specifications or any other applicable standards.

14.3.3 Fineness Modulus Fineness Modulus (FM) is used in determining the degree of uniformity of the aggregate gradation. It is an empirical number relating to the fineness of the aggregate. The higher the FM is, the coarser the aggregate is. Fineness Modulus is defined as the sum of the cumulative percentages retained on specified sieves

Effects of cement fineness on cement properties. Q. How does the fineness to which the clinker is ground affect the properties of the cement? A. Increasing the fineness increases the rate of hydration of cement, which increases the rate of gain in strength and also the rate at which heat is liberated as in Type III compared with Type I cement (ASTM C150).

Abstract : A s tudy pertaining to the effect caused on concrete, due to the change in source and fineness modulus of copper slag has been carried out. It was found that as the fineness modulus of copper slag increased, the compressive strength value of concrete in which cement was partially replaced by copper s lag, decreased to some extent.
