fineness modulas of dust

Aggregates in Concrete

For instance, a fineness modulus of 4.00 can be interpreted to mean the the fourth sieve, No. 16 in the US series, is the average size. It is important to note that the fineness modulus is just one number which only characterizes the average size of the aggregate, and different gradings may have the same fineness modulus.

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).

The larger the value, the coarser is the material.

Sieve Analysis of Soil; Its Determination, Theory .

Thus a fineness modulus of 6.00 can be interpreted to mean that the sixth sieve, 4.75 mm is the average size. The fineness modulus cannot represent the particle size distribution, but it is useful for measuring slight variations in the aggregate from the same source, i.e., as a day to day check.
