Answer rakesh kumar Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100 Fineness modulus is generally used to
Fineness modulus The same value of fineness modulus may therefore be obtained from several different particle size distributions In general however a smaller value indicates a finer aggregate Fine aggregates range from a FM of 200 to 400 and coarse aggregates smaller
Then we get the value of fineness modulus 015mm 0 5000 100 Sum 717 Therefore fineness modulus of coarse aggregates sum cumulative retained 100 717100 717 Fineness modulus of 717 means the average size of particle of given coarse aggregate sample is in between 7th and 8th sieves that is between 95mm to 19mm
