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.
Fineness modulus of aggregate is an index number which gives an idea about the finance of aggregate and is an approximate proportion of the average size of particle in the aggregate. It is found out by sieve analysis test of standard size in the laboratory.
Sample preparation for fineness modulus of sand is given as under: Take a sample of sand in a pan and placed it in the oven at a temperature of approximate 100-110°C. After drying, take the sample out from oven and note down its weight using digital weighing scale. Test Procedure: Following is the test procedure for fineness modulus of sand test:
The sand is good if its fineness modulus is in the range of to The sand with fineness modulus less than this will be called fine sand which is not good for use.

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 of fineness modulus for aggregate of different maximum sized aggregates is given below.

For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume
Jan 01, 1994 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 same strength." Before calculating FM, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample.
In this video , we will see how to do the sieve analysis and find out the Fineness Modulus of sand.

In Building Materials in Civil Engineering, 2011 (1) Grain Gradation and Coarseness of Sand. The grain gradation and coarseness of sand are determined by screen residue analysis. Grading region and fineness modulus can be used to express the gradation and the coarseness of sand particles respectively. A set of square-hole sieves whose diameters are 4.75 mm, 2.36 mm, 1.18 mm, 0.60 m,
Sep 01, 2014 What is Fineness Modulus of Aggregate? 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 Why to Determine Fineness Modulus? Fineness modulus is generally used to get an ...

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
b) As per the grading given in Table 1, the fineness modulus of sand could vary from I.2 to 2.2. However, it is preferable to have minimum fineness modulus of l-4 in case of crushed stone sands and crushed gravel sands and a F. M of 1 5 in case of naturally occurring sands. Hence,
Medium sand: fineness modulus is 3.0-2.3, the average particle size is 0.5-0.35 mm. Fine sand: fineness modulus is 2.2-1.6, the average particle diameter is 0.35-0.25 mm. Extra fine sand: fineness modulus is 1.5-0.7, and the average particle diameter is less
So, the Lawrencepur sand lies in the category of medium coarse sand; The value of fineness modulus is between 2.5 and 3.1, hence it is good fine aggregate; The graphs of the gradation curve are intersecting because the material is not well graded.
