Read MoreFeb 14, 2020· Fineness modulus gives us an overall idea whether the material is fine or coarse. It also indicates the surface area of the particles. Lower the surface area of the aggregate, the required amount of fresh cement paste to cover the aggregate particles will be less and thus less water is required. Larger value of FM is preferred for fine aggregates.

Read MoreJan 01, 1994· Before calculating FM, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample. 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.
