  • Grading of Aggregate and Fineness Modulus of grading of ...

    Fineness Modulus of grading of aggregate. Fineness modulus is an empirical factor computed from the sieve analysis. It is defined as the sum of the cumulative percentages retained on the sieves of the standard series ranging from 80mm to 150microns and dividing the sum by 100. When all particles in a sample are coarser then say 600µm, the ...

    The fineness modulus is exactly what it sounds like: a measure of how fine or coarse an aggregate is. This factor is obtained by adding the total percentages by weight of an aggregate sample retained on each of a specified series of sieves, and dividing the sum by 100. A higher FM corresponds to a coarser aggregate.

    The fineness Modulus (FM) of Coarse aggregate is higher than combined and fine aggregate. The FM of fine aggregates is lowest. And FM of combined aggregate is in between. Here, X = Coarse aggregate = Largest value. Y = Fine aggregate = Lowest value. Z = Combined aggregate = Intermediate value. Compare it with the answer.
