TransCalc Fineness Modulus Calc

Fineness Modulus (FM) is an index of the fineness of an aggregate. In general, the higher the FM, the coarser the aggregate. Fineness Modulus - The Fineness Modulus (FM) of fine, coarse, or combined aggregate is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100.

THE ROLE OF FINENESS MODULUS

Fineness modulus offers a way to quantify the average size of the aggregate particles in the concrete mix.
