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 ...

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."

11/29/2015· The fineness modulus is an index of the coarseness or fineness of an aggregate sample, but, because different grading can give the same fineness modulus, it does not define the grading. Waymouth introduced his theory of satisfactory grading on the basis of "particle interference" considerations3.9.

concept of particles size distribution in so far as they deviate from the avera size or fineness modulus as indicated by the standard deviation of the sample. Six concrete mixes 1:2:4 by weight (320 kg/m3 cement content) were designed for a given slump of (30-60) mm. The main variable being the

9/9/2010· Fineness Modulus: 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."

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.

the concept of fineness modulus (FM) for estimating the propor-tions of fine and coarse aggregates in c o n c r ete mixtures. The pre m i s e : "aggregate of the same fineness mod-ulus will require the same quantity of water to produce a mix of the same consistency and give a concrete of the same strength." Over the years, many

Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.. A fiber, a single filament of natural material, such as cotton, linen or wool, or artificial material such as nylon, polyester, metal or mineral fiber, or man-made cellulosic fibre like viscose, Modal, Lyocell or other rayon fiber is measured in terms of linear mass density, the weight of a given length of fiber.

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 defines the size of the of the aggregates on concrete mix design. There area some limits on it though. If you have high modulus of fineness, the tendency of mixture is to have ...

The sizes of coarse aggregate were 19 mm, 12.5 mm, 9.5 mm, 4.75 mm, 2.36 mm and 1.18 mm. Mixtures of local sand and Sylhet sand (1:1) and with fineness modulus of …

The overall fineness of sand is given by factor called fineness modulus. Fineness Modulus is given by division of the summation of cumulative ... Thus the object in this paper is to find the best fineness modulus of sand to get the ... the concept of fineness modulus.

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 mixtures. The premise: "aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy ...

X Aggregate – In this test find smaller and larger size filler material in construction. Fine and coarse aggregate test is find out specific gravity, water absorption, moisture content. Sieve analysis and fineness modulus give us proportioning of ingredients of concrete mix.

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 ...
