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 mm, mm, mm, mm, mm, mm, mm, mm, mm and larger increasing in the ratio of 2:1.
Study On Behaviour Of Concrete Partially Replacing Quartz Sand As Fine Aggregate ... Fineness modulus = ... 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. ...
What Is The Fineness Modulus Of Manufactured Sand. Fineness Modulus For Crush Sand Aircondi. For crushed stone or manufactured modulus astm c136 amount of material finer noas per is 1542 5 the of sand shall be not less than 1in crushed stone sands and crushed gravel sand and

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 ...
was washed natural quartz sand with a fineness modulus of, matching the lower usable zone ( to ), 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
The following root zone mix meets USGA size specifications, but you need to determine if the uniformity coefficient and fineness modulus of the material are acceptable. Sieve openings for the fineness modulus are,,,, and mm. The uniformity coefficient is D60 over D10. Sieve size % on sieve cumulative % %passing mm 0
The fineness of the sand plays an important role in the finishability of the concrete mix, and even small changes in fineness can affect finishing. The fineness modulus is a single parameter that describes the grading curve and can be useful in checking the uniformity of grading.
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 ...
Dec 09, 2017· In this video, we will see how to do the sieve analysis and find out the Fineness Modulus of sand. In this video, we will see how to do the sieve analysis and find out the Fineness Modulus of 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 .
Fine sand: fineness modulus of –, with an average particle diameter 0 35–0 25 mm; Special fine sand: fineness modulus of –, with an average particle diameter of 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 ...
For aggregates used in PCC, another common gradation description for fine aggregate is the fineness modulus. It is described in ASTM C 125 and is a single number used to describe a gradation curve. It is defined as: The larger the fineness modulus, the more coarse the aggregate.
What is the finess modulus of sand?.. Answer / dr savitha natak. Fineness modulus of sand is an index arrived based on the particle size analysis and then dividing the sum of the cumulative percentage of particles retained on the sieves by 100. it is important to note that higher the fineness modulus, higher is the coarser portion of the sand. ...
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.
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 of fine aggregate is related to term fineness modulus; most commonly modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete.
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 .
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.
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 sieve sizes are mm, mm, mm, mm, mm, mm, mm, mm, 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 ( in.) and generally between mm and mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pitrun gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural ...
Limits of Fineness Modulus. Fineness modulus of coarse aggregate varies from to And for all in aggregates or combined aggregates fineness modulus varies from to Range of fineness modulus for aggregate of different maximum sized aggregates is given below.
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.

Sieve 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 .
