Fineness modulus Wikipedia Fineness modulus In general however a smaller value indicates a finer aggregate Fine aggregates range from a FM of 200 to 400 and coarse aggregates smaller than 381 mm range from 650 to 800 Combinations of fine and coarse aggregates have intermediate values.

Apr 20 2019The same fineness modulus can represent a number of different size distributions and grading curves Therefore fineness modulus cannot be used as a description of the grading of aggregate The use of the fineness modulus in the assessment of variations from the same source or parabolic behavior of a concrete mix is of great help.
