Aggregate in Concrete - The Concrete Network

The dividing line between fine and coarse aggregate is the 3/8-inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100 (see Table 1).

Revised Application Of Fineness Modulus In Concrete ...

Preference is given to the use of water-cement ratio as the first step in the de- sign. When the fineness of combined aggregate is expressed in terms of fineness modulus instead of as gravel-sand ratio, a single determination of opti- mum fineness serves for all reasonable gradations of fine or coarse aggregates of a given type and maxi- mum size.
