Jan 01, 1994· The premise: "aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy and give a concrete of the same strength." Before calculating FM, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample.

Know MoreSieve analysis of natural and manufactured sand show that the fineness modulus of manufactured sand is greater than that of natural sand. i.e. the fine aggregate changes from zone III to zone I.
