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. Fine aggregate means the aggregate which,FINENESS MODULUS OF AGGREGATE – WHAT, WHY & HOW,,Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is. More fineness modulus value indicates that the aggregate is coarser and small value of fineness modulus indicates that the aggregate is finer. Fineness modulus of different type of sand isEffect of Fineness of Sand on the Cost and Properties of,,As fineness modulus of sand changes from 2.0 to 2.5 there is an increase in compressive strength from 43.07 to 49.00 MPa. i.e. strength increases by 14%. On the other hand by increasing Fineness Modulus from 2.5 to 3, Compressive strength increases from 49.00 to
Read MoreIt should be reminded that the fineness modulus can not reflect the quality of their grading regions. The sand with the same fineness modulus can have very different grading regions. Therefore, the particle gradation and the fineness modulus should be considered in the preparation of concrete.Fineness Modulus of Coarse Aggregates and its Calculation,Fineness modulus is the number at which the average size of particle is known when we counted from lower order sieve size to higher order sieve. So, in the calculation of coarse aggregate we need all sizes of sieves. Determination of Fineness Modulus of Coarse Aggregates. To find fineness modulus we need to perform sieve analysis and for that,Effect of Fineness Modulus of Manufactured Sand on,,sand deposits creating several environmental issues, as an alternate manufactured sand (MSand) are being used as fine aggregate in place of natural river sand. This research is mainly concentrated on gradation of fine aggregate to get required quality by examine the effect of different

This research is mainly concentrated on gradation of fine aggregate to get required quality by examine the effect of different fineness modulusFineness modulus  Wikipedia,The same value of fineness modulus may therefore be obtained from several different particle size distributions. In general, however, a smaller value indicates a finer aggregate. Fine aggregates range from a FM of 2.00 to 4.00, and coarse aggregates smaller than 38.1 mm range from 6.75 to 8.00.
Read MoreFineness 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 – 3.2What is the fineness modulus of sand  Answers,Finess Modulus is just a value (number) indicating the fineness or coarseness of the aggregate. So, a river sand (natural sand) will be in the range of2.5 or so to 2.7 and Pgravel (Pstone, Birds,(PDF) USING DIFFERENT TYPES OF FINE AGGREGATE TO,One the other hand, the low sulphate content (SO3) of the river sand which is about one sixth than the sulphate content in the normal sand in this study has also a considerable effect on optimum,
Read MoreDegree of gradation is also called fineness modulus of sand. We find fineness modulus and compare it the standard recommended values. Apparatus: The apparatus consists of six different types of sieves i.e. #4, #8, #16, #30, #50, and #100 sieve. The smallest sieve number is at the top and the others are arranged in ascending order.THE ROLE OF FINENESS MODULUS  Southport Concrete Co,Fineness modulus also provides important information about the density of the resulting concrete, as well as its compressive strength. Both of these factors must be taken into consideration when designing the concrete. For more information about the role played by fineness modulus, contact the concrete experts at Southport Concrete Corp.Effect of Fineness of Sand on the Cost and Properties of,,Since mix with so different fineness modulus of sand,,Figure 1, shows the type of slump observed.,Effect of Fineness of Sand on Flexural Strength of Concrete Flexural strength is calculated from 28 days testing of beam of size 150x150x700 mm by using following formula.

A good sand which is used in construction should have less than 3% of Silica and no organic impurities. Different construction activities requires different fineness modulus of sand. Sand used in Brick work:The sand used for Brickwork should have a fineness modulus of 1.2 to 1.5. Sand used in plastering:

[5] investigate a comparison of three maximum size grading of sandgravel and sandcrushed stone mixtures in concrete has revealed that for each type and size of coarse aggregate a constant value for fineness modulusHighstrength concrete with different fine aggregate,,Four fine aggregates from different mineralogical sources, but of similar fineness modulus, were used. Natural siliceous river sand (NS) having rounded and smooth particles was used as a reference sand. Crushed sands were selected with different petrographic characteristics (granite, limestone and dolomite) but similar grading curves.How does the fineness modulus of aggregate affect the,,Fineness Modulus is an indication grading of particle size.
