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."

8/19/2017· In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and coarse aggregates in concrete mixtures. The principle: "Aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistency and give a concrete of the same strength."

Modulus Fineness = 9(100) - 302 = 900 - 302 Modulus 100 100 = 5.98 5. Significance and Use A method of selecting mixture proportions for concrete based on the fineness modulus of the combined fine and coarse aggregate was proposed by Abrams in 1918. This method is not widely used today but the concept of being able to describe particle-size ...

METHOD OF CALCULATION OF THE FINENESS MODULUS OF AGGREGATE 1. Definition 1.1 The standard definition of fineness modulus is as follows: "An empirical factor obtained by adding the total percentages of a sample of the aggregate retained on each of a specified series of sieves, and dividing the sum by 100." Note.-

Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.

Origins of the Fineness Modulus Concept. Duff Abrams, an American materials researcher in the early part of the 20th century, was influential in studying concrete properties and characteristics. Along with defining the importance of water/cement ratio and developing the slump test, he defined fineness modulus in 1918 as a way of characterizing ...
