Jul 30 2016 Therefore fineness modulus of aggregate cumulative retained 100 275100 2.75. Fineness modulus of fine aggregate is 2.75. It means the average value of aggregate is in between the 2 nd sieve and 3 rd sieve. It means the average aggregate size is in between 0.3mm to 0.6mm as shown in below figure.
The accumulated percentage kept on each sieve is applied and the sum of the fine aggregate is subdivided by 100. To find the fine aggregate fineness modulus we require 4.75mm 2.36mm 1.18mm 0.6mm 0.3mm and 0.15mm sieve sizes. The fineness modulus of the finer aggregate is greater than the coarse aggregate fineness module.

Sep 01 2014 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. Fineness Modulus of Sand.
Fine Aggregate and Fineness Modulus. Posted 2016-10-14 In civil engineering aggregates with a particle size greater than 5 mm are coarse aggregates also known as stone aggregates with a particle size of less than 5 mm are fine aggregates also known as sand.Qualified fine aggregate should have a good gradation including fineness modulus firmness mud content sand equivalent etc.
The coarseness of sand is expressed by fineness modulus Mx defined as follows 5.1 M x A2 A3 A4 A5 A6 5A1 100 A1. The bigger the fineness modulus is the more coarse the sand is. The fineness modulus of the sand used in ordinary concrete is within 3.7 1.6.

SIEVE ANALYSIS AND FINENESS MODULUS Sampling Since the reason for sampling aggregates is to determine the gradation particle size of the aggregate it is necessary that they be sampled correctly. The results of testing will re ect the condition and characteristics of the
Jan 01 1994 ASTM C 33 requires the FM of fine aggregate to be between 2.3 and 3.1. The higher the FM the coarser the aggregate. Fine aggregate affects many concrete properties including workability and finishability. Usually a lower FM results in more paste making concrete easier to finish.
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.
Jul 20 2018 Fineness Modulus To determine the fineness modulus the contractor adds the cumulative percentage-retained values and divides the sum by 100. This process must be repeated for both coarse and fine aggregate sizes.
coarser the aggregate. The fineness modulus is computed by adding the cumulative percentages retained on the 6 in. 3 in. 1 12 in. 34 in. 38 in. No. 4 No. 8 No. 16 No. 30 No. 50 and No. 100 sieves and then dividing by 100. The fineness modulus of a fine aggregate is useful in estimating the proportions of fine and coarse aggregates in concrete mixtures.
The refractoriness of the silica sand is highest. Fineness Finer sand molds resists metal penetration and produces smooth casting surface. Fineness and permeability are in conflict with each other and hence they must be balanced for optimum results. Bench Life It is ability of the molding sand to retain its properties during storage.
