The fineness modulus is commonly used to determine the coarseness or fineness of an aggregate. A higher fineness modulus value suggests a coarser aggregate whereas a lower fineness modulus value implies a finer aggregate. Sand with a fineness modulus of more than 3.2 is usually not being used to produce great concrete.
Fineness modulus is the number at which the average size of particle is known when we counted from lower-order sieve size to higher-order sieve. So, in the calculation of coarse aggregate we need all sizes of sieves. Determination of Fineness Modulus of Coarse Aggregates To find fineness modulus we need to perform sieve analysis and for that above mentioned sieve sizes, mechanical shaker and
The Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100. Sieves sizes are: 150-μm (No. 100), 300-μm (No. 50), 600-μm (No. 30), 1.18-mm (No. 16), 2.36-mm (No. 8), 4.75-mm (No. 4), 9.5-mm (3/8-in.), 19.0-mm (3/4-in.), 37.5-mm (11/2-in.), and larger
use fineness modulus variation as a convenient means of keeping quality history data on uniformity of particle-size distribution of aggregate production, delivery, and use. Some agencies require that aggregates be processed to remain within upper and lower limits of fineness modulus. Such requirements are more frequently applicable to fine aggregate than coarse aggregate or combined
Fineness Modulus of grading of aggregate. Fineness modulus is an empirical factor computed from the sieve analysis. It is defined as the sum of the cumulative percentages retained on the sieves of the standard series ranging from 80mm to 150microns and dividing the sum by 100. When all particles in a sample are coarser then say 600µm, the
31/07/2016 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. Fine aggregate means the aggregate which
The fineness modulus of coarse aggregates is the index number of the total particle size of the coarse aggregate.By doing sieve analysis with normal sieves, it is measured.The accumulated percentage retained on each sieve is applied and the coarse aggregate valuation is given by subdividing it by 100.. The fineness module is larger than the fine aggregate, thus the fineness module of the

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 1mm-0.5mm. 2.

Fineness modulus is a ratio of the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron to this sum by 100. Fineness modulus indicates the grading of aggregates. More fineness of
The fineness modulus is defined by both CSA and ASTM. A low number indicates a fine sand, a high number a coarse sand. For supply of concrete fine aggregate, it has been found that a Fineness Modulus of between 2.3 and 3.1 will normally give satisfactory workability. It is good practice to keep the Fineness Modulus within 0.2 to ensure reasonably consistent supply.

The fineness modulus of sand shall be not less than 1.4 in case of crushed stone sands and crushed gravel sands and not less than 1.5 in case of naturally occurring sands. The various sizes of particles of which the sand is composed shall be uniformly distributed throughout the mass. The required grading may often be obtained by screening and/or by blending together either
