FINENESS MODULUS OF AGGREGATE – WHAT, WHY

2014-9-1 · Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is. More fineness modulus value indicates that the aggregate is coarser and small value of fineness modulus indicates that the aggregate is finer. Fineness modulus of different type of sand is as per given below. Type of Sand. Fineness Modulus Range. Fine Sand.

The Fineness Modulus should be between 2.3 and 3.1. FM is an index of the fineness of an aggregate-the higher the FM the coarser the aggregate. Different aggregate grading may have the same FM. FM of fine aggregate is useful in estimating proportions of fine and coarse aggregates in concrete mixtures.
