Sep 01, 2014 · 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.

Jul 20, 2018 · Generally speaking, the higher the fineness modulus, the higher the slump value — or in other words — the stiffer the concrete will be. Fineness modulus also provides important information about the density of the resulting concrete, as well as its compressive strength.

Fineness Modulus. It is the cumulative percentage retained on standard sieve 150μm or sieves No 100 and above divided by 100. It is a single factor or an empirical number which we get from the results of sieve analysis. The value of FM will not change if we add non standard sieves in standard set of sieves.

How does the fineness modulus of aggregate affect the ...

Fineness Modulus is an indication grading of particle size. More the value of FM more coarser the aggregate is. Now because density vary with particle size, and also the void spaces inside the concrete is a function of aggregate size, it is very important to have aggregate of all sizes in mix proportion for attaining good strength.
