The Grading-zone Curve of Sand. The coarseness of sand is expressed by fineness modulus ( Mx ), defined as follows: (5.1) M x = A 2 + A 3 + A 4 + A 5 + A 6 − 5 A 1 100 − A 1. The bigger the fineness modulus is, the more coarse the sand is. The fineness modulus of the sand used in ordinary concrete …

FINENESS MODULUS OF FINE AGGREGATE TxDOT Designation: Tex-402-A Effective Date: August 1999 1 SCOPE 11 This method determines the fineness modulus of concrete fine aggregate used in evaluation of natural and manufactured sands for portland cement concrete 12 The values given in parentheses (if provided) are not standard and may not be exact

The sand produced by peakedness Sand Making Equipment has excellent particle shapes, gradation continuous and fineness modulus of stability, finished sand product's solid volume rate can be increased by 2% - 3% over natural sand, when mixed with concrete and asphalt, it can effectively reduce the shrinkage rate, improve the strength of commercial concrete and asphalt to reach more stable and

Feb 01, 2001 · Ideal and optimum fineness moduli are used in combination with the geometrical gradation of aggregates to establish the mix proportioning of mass concrete. The ideal and optimum fineness moduli are experimentally determined for each maximum size of aggregate (MSA) by making concrete mixtures with aggregates of different fineness modulus and

Fineness Modulus Of Sand | Sieve Analysis Of Fine Aggregate | F. M. Va…

Determination of Fineness Modulus of Sand To determine the fineness modulus, we need standard sieves, mechanical sieve shaker (optional), dry oven and digital weight scale. Sample preparation Take a sample of fine aggregate in pan and placed it in dry oven at a temperature of 100 – 110 o C. After drying take the sample and note down its weight.

The fineness modulus of ordinary concrete sand is in the range of 3.7-1.6, and medium sand is suitable. Or use coarse sand and a small amount of fine sand, the ratio is 4:1. Coarse sand: The fineness modulus is 3.7-3.1, and the average particle size is 0.5mm or more.

FINENESS MODULUS (FM) - The fineness modulus (FM) is a factor obtained by adding the percentages of material in a sample of aggregate that is retained on each of the following sieves: #100, #50, #30, #16, #8, #4, 3/8", ¾", 1 ½", 3", 6". The result is divided by 100 to arrive at the fineness modulus. For conventional concrete the

Fineness Modulus - an overview | ScienceDirect Topics

An example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate, the table indicates that 0.71m3 of coarse aggregate, on a dry-rodded basis, may be used in each cubic meter of concrete. The required dry mass is, therefore, 0.71 x 1600 = 1,136kg."

Fine aggregate (sand) grading affects consistence and finishability. Fineness Modulus (FM) is an empirical calculation used to support the optimisation of a concrete mix design. It is used to determine 'degree of uniformity of the grading'. This can create a relationship between grading and consistence and/or the amount of cement or water to fill the voids.

Mix design M-25 grade of concrete was used to study the different harden properties of to be used as fine aggregate in concrete. The thermal power plants are the main source of power generation in India. These thermal Sand Pond Ash Fineness modulus 5.76 6.79 3.75 3.10 Specific gravity 2.75 2.67 2.62 1.93 Water absorption 0.601 0.601 1

optimum fineness modulus (F.M)*. The curve in Fig. 1 was drawn from Wilk and Grants 2 table of values published in rock products in February, 1948. The compressive strengths shown were obtained from 3 X 6 inch cylinders made from a dry (concrete block) mix, cured in water 21 days and dried to constant weight before testing. Each

Dec 15, 2020 · The fineness modulus specifies the average size of the sand and aggregate particles for the mixing of concrete. However, the size will be beneficial in understanding how easily the concrete pours and spreads, along with its strength and durability once cured.

get river sand of consistent quality in terms of grading requirements and limited silt / clay content. In case of manufactured sand with well-designed screening system the required grading and fineness modulus (2.4 to 3.1) can be achieved consistently . It must be noted that properly graded
