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. Suppose ...

Get PriceThe 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 ...

Get Pricesands, the permissible limit on 150 micron IS Sieve is increased to 20 percent. This does not affect the 5 percent allowance permitted in 5.1. 5.2 The fineness modulus of sand shall be not less than I.4 in case of crushed stone sands and crushed gravel sands and not less than I.5 in

Get PriceIt is pointed out that manufactured sand is anytime better than river sand. The particle shape is cubical, which is almost closer to rounded river sand. Another issue associated with river sand is that of obtaining required grading with a fineness modulus (FM) of 2.4 to 3.1. Generally FM of 2.2 to 2.6, 2.6 to

Get PriceFineness 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

Get PriceFor aggregates used in PCC, another common gradation description for fine aggregate is the fineness modulus. It is described in ASTM C 125 and is a single number used to describe a gradation curve. It is defined as: The larger the fineness modulus, the more coarse the aggregate.

Get PriceNatural sand was replaced by M-sand at levels of 20, 40, 60, 80, and . Flow test was conducted on all mortars and the effect of M-sand replacement on flow characteristics was studied.

Get PriceFineness modulus of 7.17 means, the average size of particle of given coarse aggregate sample is in between 7 th and 8 th sieves, that is between 10mm to 20mm. Limits of Fineness Modulus. Fineness modulus of coarse aggregate varies from 5.5 to 8.0. And for all in aggregates or combined aggregates fineness modulus varies from 3.5 to 6.5. Range ...

Get PriceTo determine the fineness modulus of fine aggregate. Equipment and Apparatus . Set of sieve; Weighing machine ; Tray; Sand Specimen; Procedure. Take s suitable sample of fine aggregate and take the weight of it. Now place the sample in the set of IS sieves arrange in descending order 10 mm, 4.75 mm, 2.36mm, 1.18 mm, 600 microns, 300 microns and ...

Get PriceIt is obtained when Fineness Modulus is about 2.7. The net cost of Concrete reduces when FM of sand increases. It reduces by about 6.5% for an increase of FM from 2.0 to 3.0. As the fineness modulus of Sand increases, the Cost/Benefit Ratio reduce by a very large factor. This .

Get PriceFineness modulus (FM) of aggregates can be an intimidating term, but it's just an empirical value that describes the average size of particles in a sample of aggregate. This factor provides a basis to select estimated proportions for concrete mix design, but its real influence is not always understood.
