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

What is Fineness Modulus of Sand (Fine Aggregate) and

Jul 30, 2016· What Is Fineness Modulus of Sand? 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.

fineness modulus : définition de fineness modulus et

Fineness modulus is a measurement of the coarseness or fineness of a given aggregate. For a fine aggregate, FM is calculated from the cumulativepercentages of aggregate retained on sieves No.4, 8, 16,30, 50, 100 divided by 100. FM is an index of the fineness of an aggregate-the higher the FM the coarser the aggregate.
