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 ...
Study On Behaviour Of Concrete Partially Replacing Quartz Sand As Fine Aggregate ... Fineness modulus = 4.2. ... We are hopeful that this will be of great use to all engineers who are looking for more information on "Behaviour Of Concrete Partially Replacing Quartz Sand As Fine Aggregate. ...
was washed natural quartz sand with a fineness modulus of 2.18, matching the lower usable zone (1.55 to 2.20), according to the Brazilian NBR 7211 standard [7]. This size was chosen because it provides smaller segregation of the expanded clay in LWAC. This can be explained by the higher surface area of finer sands, which
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.
To find the fineness modulus of fine aggregate we need sieve sizes of 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus of finer aggregate is lower than fineness modulus of coarse aggregate. Determination of Fineness Modulus of Sand To determine the fineness modulus, we need standard sieves, mechanical sieve shaker (optional ...
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 .
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 P-gravel (P-stone, Birds ...
This is commonly found by the Method of Fineness Modulus. The method can be used to determine fineness modulus of coarse aggregates, fine aggregates, and all-in aggregates, i.e., mixed aggregates. In this method, a convenient weight of the sample is taken .

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.

The Fineness Modulus (FM) is an index number which is roughly proportional to the average size of the particles in an aggregate sample. It is obtained by adding the cumulative percentages coarser ...
Sieve Analysis.As we know that the Fineness modulus is a measurement of the coarseness or fineness of a given aggregate, higher the FM the coarser the aggregate. The above table is showing us that the Laurence pure sand is coarser then Chenab sand .
Fineness Modulus The fineness modulus is an indicator of the fineness of an aggregate and is most used for evaluating fine aggregates. The higher the number, the coarser the aggregate. The fineness modulus is computed by adding the cumulative percentages retained on the 6 .
Aug 14, 2019· What is Fineness Modulus of Sand? 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 .
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 ...
Quartz " dune sand " with rolled grains, a rounded shape and smooth surfaces, it has a fineness modulus of 0.8, an apparent density of 1.46 g/cm maximum grain size of 0.63 mm. Table 2 summarises the chemical composition of TABLE2. Chemical composition of quartz "dune sand" For all mortar mixtures, the Sand to cement ratio weight.
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 ...
The Fineness modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100.The sieve sizes are 0.15 mm, 0.3 mm, 0.6 mm, 1.18 mm, 2.36 mm, 4.75 mm, 9.5 mm, 19.0 mm, 38.1 mm and larger increasing in the ratio of 2:1.
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural ...
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 .
Effect of ground quartz sand on properties of hig. The aggregate consists of 520 mm crushed rock, with the river quartz sand having the fineness modulus of 2 5 Four types of natural quartz sand are used for producing GQS with the Blaine specific area of 283551 m 2 kg, having SiO 2 content of 99%, 94 5%, 92 1%, and 84 7%, respectively.

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.
In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtures. 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 ...
