The Fineness Modulus (FM) is an index number which is roughly proportional to the average size of the particles in an aggregate sample. It is obtained by adding the cumulative percentages coarser ...

Grading, fineness modulus and plasticity index shall be tested to meet the requirements prescribed. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

In Building Materials in Civil Engineering, 2011 (1) Grain Gradation and Coarseness of Sand. The grain gradation and coarseness of sand are determined by screen residue analysis. Grading region and fineness modulus can be used to express the gradation and the coarseness of sand particles respectively. A set of square-hole sieves whose diameters are 4.75 mm, 2.36 mm, 1.18 mm, 0.60 m, …

Sometime it may happen that, the aggregate available at site is not conforming to the desired grading. In such case two or more aggregates from different sources may be combined to get the required grading. Fineness modulus value can be used as a technical way to blend coarse aggregate with fine aggregate to produce desired […]

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 ...

Jun 02, 2012· Degree of gradation is also called fineness modulus of sand. We find fineness modulus and compare it the standard recommended values. Apparatus: The apparatus consists of six different types of sieves i.e. #4, #8, #16, #30, #50, and #100 sieve. The smallest sieve number is at the top and the others are arranged in ascending order.

For aggregates used in PCC, another common gradation description for fine aggregate is the fineness modulus. It is described in ASTM C 125 and is a single number used to describe a gradation curve. It is defined as: The larger the fineness modulus, the more coarse the aggregate.
