The Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100. Sieves sizes are: 150-μm (No. 100), 300-μm (No. 50), 600-μm (No. 30), 1.18-mm (No. 16), 2.36-mm (No. 8), 4.75-mm (No. 4), 9.5-mm (3/8-in.), 19.0-mm (3/4-in.), 37.5-mm (11/2-in.), .

17.10.2013· Fineness Modulus Method of Concrete Mix Design The index number, which describes the relative sizes of coarse and fine aggregates, is called as fineness modulus (FM). Fineness modulus is determined separately by sieving coarse and fine aggregates through the following set of sieve. IS sieves for coarse aggregates are 80 mm, 40 mm, 20 mm, [.]

01.01.1994· 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 same strength." Before calculating FM, lab technicians perform a sieve .

the mix. The effect of changing fineness modulus of fine aggregate on SCC properties is not clear on hardened concrete, while it is more clear on fresh concrete, it has been noticed that concrete mixes prepared with 10 mm maximum size aggregate lead to higher strength about 18%for compressive strength and the fineness modulus of 3.1 gives higher results than other fineness modulus .
Sl.No. Fineness Modulus Nature of sand 1 2.2 – 2.6 Fine sand 2 2.6 – 2.9 Medium sand 3 2.9 – 3.2 Coarse sand Sand having a fineness modulus more than 3.2 will be unsuitable for making satisfactory concrete. The fineness modulus values obtained for sand, quarry dust and coarse aggregate are given in Tables 3.7 to 3.9.
Fineness Modulus is an indication grading of particle size. More the value of FM more coarser the aggregate is. Now because density vary with particle size, and also the void spaces inside the concrete is a function of aggregate size, it is very i...

The significance of fineness modulus (FM) is in specifying the proportions of fine and coarse aggregates when designing concrete mixes. The higher the value of FM, the coarser the aggregate. Generally, a lower FM results in more paste, making the concrete easier to finish. However, FM does not define the grading curve and different gradings could have similar FMs Suprenant, 1994). The .
