The Importance of Fineness Modulus| Concrete Construction ,
In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtur 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 .

Aggregate Gradation Optimization - Literature Search
want a return to coarser, higher fineness modulus sands to get away from water demand related shrinkage issu Most reports of the use of aggregate optimization point out the benefits of using a more well-graded material, including less paste and hence less concrete shrinkage, greater strengths, better pumpability, and enhanced finishability .
Gradation Test | Sieve Analysis of Fine and Coarse Aggregates
Jun 02, 2012· The sand is good if its fineness modulus is in the range of 23 to 31 The sand with fineness modulus less than this will be called fine sand which is not good for use The sand with fineness modulus greater than this will be called coarse sand, which is again not good for use
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 siev The cumulative percentage retained on each sieve is added and
