Fine sand: fineness modulus of 2.2–1.6, with an average particle diameter 0 35–0 25 mm; Special fine sand: fineness modulus of 1.5–0.7, with an average particle diameter of 0.25 mm or less. The larger the fineness modulus is, the coarser the sand will be. The appropriate range of fineness modulus of the sand aggregate used in normal ...

F 1 = Fineness modulus value of fine aggregate. F 2 = Fineness modulus value of coarse aggregate. F = Fineness modulus value of combined aggregate. After finding the percentage of fine aggregate to be combined with the coarse aggregate by the above formula, their proportion can be …

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 56.83 MPa resulting in 16% increase in strength.

CHAPTER 2 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.

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 ...

Aug 26, 2018· Determination of Fineness Modulus of Fine Aggregate - Civil Feeds. The fineness modulus of Fine Aggregate is 2.44. For a good fine aggregate, the FM should be between 2.3 and 3.1 (ASTM Range for fine aggregates).Our result lie in this range as the graph shows that our sample is lies b/w maximum and minimum cumulative percentage passing.

What is Fineness Modulus of Coarse Aggregates? Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is …

For any type of mix proportioning sieve analysis results and fineness modulus is required. here is the excel sheet which includes calculations of fineness modulus. Hope it will consume less time in case of repetitive calculations. Excel Sheet For Sieve Analysis Of Aggregate And To Calculate Fineness Modulus- engineeringcivil.com

Sep 01, 2014· Fineness Modulus of Sand Why to Determine Fineness Modulus? 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 is as per ...

Jul 20, 2018· 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.

Fineness Modulus And Particle Size Analysis Of Fine And Coarse Aggregate ... Fineness modulus is an impurical factor which is 100 th of the sum of cumulative percentage of the fraction of a sample retain on each successively in the order. ... The sand for fine aggregate is well graded or not well graded.

Jun 30, 2010· 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 …

Jan 01, 2019· The Fineness Modulus is typically used to describe sand and is an input to the ACI 211 mixture design method. This video explains what the Fineness Modulus is and how people use it.

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 is not a precise value, as it provides a way to estimate the amount of aggregate needed to proportion mix designs. Fineness modulus is determined using percentages of the size fractions from the sieve analysis and calculated for any designated series of sieve sizes.

than river sand. The particle shape is cubical, which is almost closer to rounded river sand. Another issue associated with river sand is that of obtaining required grading with a fineness modulus (FM) of 2.4 to 3.1. Generally FM of 2.2 to 2.6, 2.6 to 2.9 and 2.9 to 3.2 indicates that the sand …
