### Sieve Analysis of Coarse and Fine Aggregates

31/08/2020· Larger value of FM is preferred for fine aggregates. For a good fine aggregate, the FM should be between 2.3 and 3.1 (ASTM Range for fine aggregates). A FM of 4 can be interpreted to means that the fourth sieve from bottom i.e. sieve No. 16 is the average size of the aggregate

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

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.

Cylindrical samples (100 mm x 200 mm) were made with different sand to aggregate (s/a) volume ratios (0.36, 0.40, and 0.44); W/C (0.45, 0.50, 0.55) and cement contents (351 kg/m3; 372 kg/m3, and 395 kg/m3). The coarse aggregates were slag aggregate or brick aggregate. In this study, partial replacement

In general, however, a smaller value indicates a finer aggregate. Fine aggregates range from a FM of 2.00 to 4.00, and coarse aggregates smaller than 38.1 mm range from 6.75 to 8.00. Combinations of fine and coarse aggregates have intermediate values. Fineness modulus of combined aggregates

01/01/1994· FM is the sum of the total percentages retained on each specified sieve divided by 100. ASTM C 33 requires the FM of fine aggregate to be between 2.3 and 3.1. The higher the FM, the coarser the aggregate. Fine aggregate affects many concrete properties, including workability and finishability.
