What is Fineness Modulus of Sand (Fine …
Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.

The experimental study on use of CBA (specific gravity=1.67 g/cm 3 and fineness modulus =1.55) as replacement of natural sand conducted by Andrade et al. (2007) reveals 25% decrease in 28-day density of concrete on inclusion of 100% CBA.
What is Fineness Modulus and how to calculate it …
Fineness modulus gives the idea about how course or fine the sand is. Lower FM indicates fine sand and higher FM indicates courser sand.Fine sand requires more cement paste due to high surface area and tendency to develop crack. On the other hand course sand produces a concrete mixture that is harsh and difficult to finish and will cause segregation.Therefore recommended FM range is 2.3 to 3.1.

Fineness modulus - Wikipedia
The Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100. Sieves sizes are: 150-μm (No. 100), 300-μm (No. 50), 600-μm (No. 30), 1.18-mm (No. 16), 2.36-mm (No. 8), 4.75-mm (No. 4), 9.5-mm (3/8-in.), 19.0-mm (3/4-in.), 37.5-mm (11/2-in.), and larger ...

Fineness Modulus - Islamic University of Gaza
Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subdivided by 100 gives the value of fine aggregate. To find the fineness modulus of fine aggregate we need sieve sizes of 4.75mm, 2.36mm, 1.18mm, 0 ...
