Feb 10, 2015· Step-1 (Calculate Fineness Modulus of Fine Aggregate) Sieve the fine aggregate using sieves ranging from 80 mm to 150 micron. Calculate the cumulative percentage of retained aggregate on each sieve. Add all the values of Percentage of retained on each sieve. Divide the sum, calculated as above, by 100. This gives the fineness modulus value of
The information obtained from fineness modulus is helpful in the following ways; Sieve Analysis. 1- Fineness modulus tells us directly whether the material is well-graded or gap-graded. 2- Fineness modulus gives us an overall idea whether the material is fine or coarse. Higher the value of FM ,coarser will be the aggregate.
If the test aggregate gives higher fineness modulus the mix will be harsh and if on the other hand gives a lower fineness modulus it gives uneconomical mix . Effective Size of Aggregates Effective size (in microns) is the maximum particle size of the smallest 10% of the aggregate or it is the sieve opening corresponding to 10% finer and is
In other words, coarser the aggregate, higher the fineness modulus. The maximum value of fineness of coarse aggregate is found to be 8.0 and for coarse sand 3.5. The fineness modulus for fine aggregate varies from 2.0 to 3.5, for coarse aggregate from 5.5 to 8.0 and for all in aggregate 3.5 to 6.5.

The fineness modulus cannot represent the particle size distribution, but it is useful for measuring slight variations in the aggregate from the same source, i.e., as a day to day check. Based on the practical experience, the fineness modulus of fine aggregate should be between 2 to 3.5 and of coarse aggregate between 3.5 to 8.
