Khaleel et al., [14], presented the effect of three types of coarse aggregate ...
· Fine aggregate is sand used in mortars. Coarse aggregate is broken stone used in concrete. The size of the fine aggregate is limited to maximum mm (4800 microns) beyond which it is known as coarse aggregate. Fineness modulus is only a numerical index of fineness, giving some idea about, the mean size of the particles in the entire body of ...
· Determination of fineness modulus of fine aggregate. Particle Size Distribution of Fine Aggregates is the operation of dividing a sample of aggregate into various fractions each consisting of particles of the same size. The sieve analysis is conducted to determine the particle size distribution in a sample of aggregate, which we call gradation.
Fineness modules() =685/100 = ) Find the of coarse aggregate and fine aggregate form the sieve analysis data as given in the table below: Weight of sample = 15 kg. Solution:Coarse aggregate
· Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is. More fineness modulus value indies that the aggregate is coarser and small value of fineness modulus indies that the aggregate is finer. Specific Surface of Aggregate. The surface area per unit weight of the material is termed as specific surface. This is an indirect measure of the aggregate .
Fineness ModulusThe Fineness Modulus (FM) of fine, coarse, or combined aggregate is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100. The specified sieves for determining FM are: 150 μm (No. 100), 300 μm (No. 50), 600 μm (No. 30), mm (No. 16), mm (No. 8), mm (No. 4), mm (3⁄8 in.), ...
· fineness modulus (FM) of aggregate is an inde number used to indie the average size of particles in aggergates . the FM is found as sum of cumulative % (C%) of the masses of aggregate retained on a set of IS sieves ( 80 mm,40 mm,20 mm,10 mm, mm, mm, mm,600 micron,300 micron,and 150 micron.) and divided by one hundred . mathmatically,
Calculate the fineness modulus of this fine aggregate sample. Report your answer to the nearest 1 decimal place (tens). Sieve Size, Retained Mass, % Retained Cumulative % % Passing mm (US) Grams on Sieves retained on seives (1/2") (3/8") (#4) (#8) ; Question: Calculate the fineness ...
· Hello Friends, This is Mukesh from Learning will tell you in today's post, Determination of Fineness Modulus of a Sample of Fine Aggregate in a very easy way. Objective of Experiment. The object of this experiment is to determine the fineness modulus and hence to plot the particle size distribution curve for the sample of fine aggregate supplied.
Fineness modulus of fine aggregate. Fineness modulus is a number that gives us the understanding of the particle size of aggregate. the basic knowledge from the fineness modulus is, the lower the fineness modulus, the finer the particle and the higher the fineness modulus, the coarser the particle. But, is it possible that a single number can adequately describe the gradation curve. Is it a ...
· TO DETERMINE THE FINENESS MODULUS AND AVERAGE SIZE OF GIVEN SAMPLE OF CONCRETE AND FINE AGGREGATE 1 APPARATUS REQUIRED . IS sieves of size 80 mm,40 mm,20 mm,10 mm, mm, mm, mm,600 micron,300 micron,and 150 micron. mechanical /semi mechanical sieve shaker. weighting balance; 2 THEORY sieve analysis is the operation of dividing a sample of aggregates .
· The Fineness Modulus of Sand is an index number that indies the mean size of the sand particles. It is calculated by performing the sieve analysis test with standard IS sieves. The fineness modulus of sand ranges from to To find the fineness modulus of fine aggregate required IS sieve are sizes of ,, ...
The fineness modulus of fine aggregate is and of coarse aggregate is and the desired fineness modulus of mixed aggregate is What is the amount of fine aggregate to be mixed with one part of coarse aggregate? Free Practice With Testbook Mock Tests. GATE CE Test Series 2022. 155 Total Tests | 8 Free Tests.
· This gives the fineness modulus value of fine aggregate. Let it be F 1. Step2 (Calculate Fineness Modulus of Coarse Aggregate) Sieve the coarse aggregate using sieves ranging from 80 mm to 150 micron. Calculate the cumulative percentage of retained aggregate on each sieve. Add all the values of Percentage of retained on each sieve. Divide the sum, calculated as above, by 100. This .
· Surface Area ∝ 1/(Fineness Modulus) Larger value of FM is preferred for fine aggregates. For a good fine aggregate, the FM should be between and (ASTM Range for fine aggregates). A FM of 4 can be interpreted to means that the fourth sieve from bottom sieve No. 16 is the average size of the aggregate particles in the given sample.

The Fineness Modulus is used in US practice and is a measure of the grading of fine aggregates. It can be calculated from a sieve analysis by adding the cumulative percentages of fine aggregates retained on the following sieve sizes;,,,, and This value is then divided by 100 to give the fineness modulus.
· Fineness modulus is an index indiing the degree and type of grain size of the fine aggregate, and is an empirical number obtained by adding the total percentage of aggregate sample retained on each of the specified series of sieves and dividing the total by 100. The value is not equal to the average particle size, but it can accurately reflect the thickness of sand. The larger the fineness ...
