• ### Fineness modulus Wikipedia

01/08/2006· 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

• ### What is Fineness Modulus of Sand (Fine Aggregate) and

31/07/2016· 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. Fine aggregate means the aggregate which

What Is Fineness Modulus of Sand (Fine Aggregate)? 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.

• ### FINENESS MODULUS OF AGGREGATE WHAT, WHY &

01/09/2014· What is Fineness Modulus of Aggregate? 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 of Sand Why to Determine Fineness Modulus? Fineness modulus is generally used to get an idea of how coarse or

• ### (PDF) METHOD OF CALCULATION OF THE FINENESS

Many agencies use fineness modulus variation as a convenient means of keeping quality history data on uniformity of particle-size distribution of aggregate production, delivery, and use. Some agencies require that aggregates be processed to remain within upper and lower limits of fineness modulus. Such requirements are more frequently applicable to fine aggregate than coarse aggregate or
