Engineers Head-Quarter: FM(Fineness Modulus of Aggragate)

Jun 05, 2016· Fineness Modulus of Sand WHY TO DETERMINE FINENESS MODULUS? 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.

Sieve Analysis of Soil; Its Determination, Theory

Fineness Modulus: Fineness modulus is a single factor computed from the sieve analysis and is defined as the sum of the cumulative percentages retained on the sieve of the standard series divided by 100. The fineness modulus can be looked upon as a weighted average size or a sieve on which the material is retained, and the sieves being counted from the finest.

Can Changes in Fine Aggregate Affect Concrete

The fineness of the sand plays an important role in the finishability of the concrete mix, and even small changes in fineness can affect finishing. The fineness modulus is a single parameter that describes the grading curve and can be useful in checking the uniformity of grading.
