Jan 01, 1994 The Importance of Fineness Modulus. In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtures. 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 fineness modulus of coarse aggregates is the index number of the total particle size of the coarse aggregate.By doing sieve analysis with normal sieves, it is measured.The accumulated percentage retained on each sieve is applied and the coarse aggregate valuation is given by subdividing it by 100.. The fineness module is larger than the fine aggregate, thus the
Fineness Modulus of Fine Aggregate. Fine aggregates is the sand used in mortars. The size of the fine aggregate is limited to maximum 4.75mm beyond which it is known as coarse aggregates. Fineness modulus is only a numerical index of fineness that gives some idea about the mean size of the articles in the entire body of concrete.
