•Fine aggregate means the aggregate which passes through sieve. •To find the fineness modulus of fine aggregate we need sieve sizes of,,,, and •Fineness modulus of finer aggregate is lower than fineness modulus of coarse aggregate.
The fineness modulus of aggregate is simply a measurement of the average size of the aggregate. It can be calculated with the help of different sizes of the sieve. Now, let us see some numerical Examples to calculate the fineness modulus of aggregate.
· Suppose,Fineness modulus of fine aggregate is It means the average value of aggregate is in between the 2nd sieve and 3rd sieve from bottom. It means the average aggregate .
The fineness modulus of fine aggregate is and of coarse aggregate is and the desired fineness modulus of mixed aggregate is What is the amount of fine aggregate to be mixed with one part of coarse aggregate?

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 cumulative percentage retained on 300µm, 150µm ...
Fine aggregate (sand) grading affects consistence and finishability. Fineness Modulus (FM) is an empirical calculation used to support the optimisation of a concrete mix design. It is used to determine 'degree of uniformity of the grading'. This can create a relationship between grading and consistence and/or the amount of cement or water to fill the voids. An example would be that sand ...
· Fineness modulus is an index indiing the degree and type of grain size of the fine aggregate, and is an empirical number obtained by adding the total percentage of aggregate sample retained on each of the specified series of sieves and dividing the total by 100. The value is not equal to the average particle size, but it can accurately reflect the thickness of sand. The larger the fineness ...
· fineness modulus (FM) of aggregate is an inde number used to indie the average size of particles in aggergates . the FM is found as sum of cumulative % (C%) of the masses of aggregate retained on a set of IS sieves ( 80 mm,40 mm,20 mm,10 mm, mm, mm, mm,600 micron,300 micron,and 150 micron.) and divided by one hundred . mathmatically,
· Hello Friends, This is Mukesh from Learning will tell you in today's post, Determination of Fineness Modulus of a Sample of Fine Aggregate in a very easy way. Objective of Experiment. The object of this experiment is to determine the fineness modulus and hence to plot the particle size distribution curve for the sample of fine aggregate supplied.
Range of Values The same value of fineness modulus may be obtained from several different particlesize distributions. In general a small value indied a fine material while a large value indies a coarse material. The value for tine aggregates commonly ranges from to and for coarse aggregate from to when all the material is finer than the 11/2in. () sieve ...

· Surface Area ∝ 1/(Fineness Modulus) Larger value of FM is preferred for fine aggregates. For a good fine aggregate, the FM should be between and (ASTM Range for fine aggregates). A FM of 4 can be interpreted to means that the fourth sieve from bottom sieve No. 16 is the average size of the aggregate particles in the given sample.
Fineness modulus of fine aggregate. Fineness modulus is a number that gives us the understanding of the particle size of aggregate. the basic knowledge from the fineness modulus is, the lower the fineness modulus, the finer the particle and the higher the fineness modulus, the coarser the particle. But, is it possible that a single number can adequately describe the gradation curve. Is it a ...
