Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is. More fineness modulus value indicates that the aggregate is coarser and small value of fineness modulus indicates that the aggregate is finer. Fineness modulus of different type of sand is as per given below. Type of Sand. Fineness Modulus Range. Fine Sand.
Fineness modulus (by weight) 3.03 fineness modulus (by volume) = 3.23 A fineness modulus of 3.23 by volume as shown in Table 3.1 indicates a considerably coarse grading than that normally associated with the fineness modulus of 3.03 by weight.

Fineness Modulus of Sand for Concrete. Fineness of fine aggregate is related to term fineness modulus; most commonly sand. Fineness modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete.
Comparison of percentage improvement of optimized sands. • The S-6 sand (fineness modulus of 2.68) gives the compressive strength lower than the S-7 sand (fineness modulus of 1.94) due to the high percentage of calcium (81.8%) and low percentage of silica (6.7%). In case of S-5 sand, the effect is not pronounced as it has 29% of silica ...
The fineness modulus of aggregate is simply a measurement of the average size of the aggregate. It can be calculated with the help of different sizes of the sieve. Now, let us see some numerical Examples to calculate the fineness modulus of aggregate.

Definition 4.2 As noted in the standard definition of 1.1 The standard definition of fineness fineness modulus (para 1.1) and the example modulus is as follows: shown in para 4.1, the fineness modulus is based "An empirical factor obtained by adding on the percentages of aggregates retained on a the total percentages of a sample of the ...
Fineness modulus of fine aggregate varies from 2.0 to 3.5mm. Fine aggregate having fineness modulus more than 3.2 should not considered as fine aggregate. Various values of fineness modulus for different sands are detailed below. Type of sand Fineness modulus range Fine sand 2.2 – 2.6 Medium sand 2.6 – 2.9 Coarse sand 2.9 – 3.2
The Importance of Fineness Modulus. 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 Fineness Modulus is an index number that indicates the mean size of the sand particle. It is calculated by the sieve analysis test with standard IS sieves. The fineness modulus of sand ranges from 2.2 to 3.2. The formula for its calculation is, Fineness modulus of Sand = (Cumulative % retained) / 100.

Therefore, fineness modulus cannot be used as a description of the grading of aggregate. When the use of the fineness modulus in the assessment of variations from the same source or parabolic behavior of a concrete mix is of great help. It reduces the ambiguity in the classification of fineness of sand.
According to the fineness modulus (MX), the specifications of machine-made sand can be divided into 4 types: coarse, medium, fine and extra fine: 1. Coarse Sand: the fineness modulus is 3.7-3.1, and the content of particles larger than 0.5mm exceeds 50% of the total weight, and the average particle size is …

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
But in case of fully saturated sand the water films are broken and the volume becomes equal to that of dry sand. Fineness Modulus. Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100.
define fineness modulus of sand zionhomes.co. 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 fine
35 synonyms of fineness from the Merriam-Webster Thesaurus, plus 81 related words, definitions, and antonyms. Find another word for fineness. Fineness: the quality or state of being little in size.
The fineness modulus of a sample of aggregate is an index number which is roughly proportional to the average size of particle in the aggregate, that is, coarser the aggregate the higher the fineness modulus.
