Fineness Modulus of Fine Aggregate: The sand fineness module (fine aggregate) is an index number describing the mean size of sand particles. By doing sieve analysis with normal sieves, it is measured.. The accumulated percentage kept on each sieve is applied and the sum of the fine aggregate is subdivided by 100.. To find the fine aggregate fineness modulus, we require 4.75mm, 2.36mm,

MoreAn example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate, the table indicates that 0.71m3 of coarse aggregate, on a dry-rodded basis, may be used in each cubic meter of concrete.

MoreJan 01, 1994· 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 concrete of the same strength."

MoreFineness 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 sieve analysis test of standard size in the laboratory.

MoreSep 01, 2014· Fineness Modulus of Sand Generally sand having fineness modulus more than 3.2 is not used for making good concrete. Fineness modulus can also be used to combine two aggregate to get the desirable grading. Fitness modulus of mixed aggregate with maximum size 20 mm is 4.70 -5.10. qaz September 13, 2017 Reply.

MoreIn the present study we have selected M30 Grade of concrete mix. To find out the effect of fineness modulus (FM) of sand on concrete, sand of different FM from 2.0 to 3.0 is chosen. Two sizes of coarse aggregate particles: i.e. 20 & 10 mm, which are generally used in standard concrete mix, were chosen for the investigations. Concrete Mix Selected:

MoreOct 26, 2016· A Concrete technologist always needs F.M. for design mix of concrete F.M. of fine aggregate is vital for him. Fineness modulus of sand (fine aggregate) is an index number which represents the mean

MoreFineness modulus of sand ranges from 2.2 to 3.2. To find the fineness modulus of sand required IS sieve are sizes of 4.75mm. 2.36mm, 1.18mm.0.6mm, 0.3mm, and 0.15mm.. Read More: Flakiness and Elongation Index Test of Coarse Aggregat e

MorePm = Fineness modulus of mix aggregate. Minimum voids Method. The minimum void method is based on the principle that the concrete with the minimum voids is the densest and most durable. The amount of fine aggregate should be such as to fill the voids. Conclusion. I hope now you understood concrete mix ratio and proportioning of concrete.

MoreACI Mix Design Step 7 -Estimation of coarse aggregate content • The percent of coarse aggregate to concrete for a given maximum size and fineness modulus is given in Table. • The value from the table multiplied by oven dried weight of coarse aggregate required per cubic foot of concrete. • Volume of coarse aggregate = 0.63 x 27 (ft3/yd 3)

MorePrinciples of Concrete & Concrete Mix Design- IS 10262. Concrete Concrete is an intimate mixture of: Cement, Sand (Fine Aggregate), Fineness Modulus of the Aggregate concrete Assumed Standard Deviation M 10 3.50 N/ mm 2 M 15 M 20 4.00 N/ mm2 45 M

More6. Dry the sample again to a constant weight on a hot plate or in an oven at a temperature of 230°F (110 ºC), then accurately weigh and record. 7. Separate the sample into individual sizes using the proper sieves. The sieves normally used are the standard 8 inch (200 mm) sieves.

MoreFeb 26, 2018· 4. Grade of combined aggregates: Single sized aggregate may lead the bleeding and segregation of the concrete mix and subsequent strength loss. 5. Fineness modulus: In order to get proper workability and strength, the fineness modulus value for fine and coarse aggregate should be within the prescribed value. 2/26/2018 Dr.V.Kannan 8 9.

Moreconcrete consisting sand with fines content of 2%, 4%, 6%, 8%, 10% and 12% with three constant water/cement ratios of 0.55, 0.60 and 0.70 were prepared for the study. The amounts of coarse aggregate used were kept constant for all batches. The concrete were mixed using 1m3 drum concrete mixer. Workability test: Slump measurement was taken

MoreThe bigger the fineness modulus is, the more coarse the sand is. The fineness modulus of the sand used in ordinary concrete is within 3.7 ~ 1.6.And if M x is within 3.7 ~ 3.1, it is coarse sand; if M x is within 3.0 ~ 2.3, it is medium sand; if M x is within 2.2 ~ 1.6, it is fine sand; and if M x is within 1.5-0.7, it is superfine sand which should be considered specifically when concrete is

Moreconcrete for different coarse aggregates and fineness moduli of fine aggregates ACI Mix Design 8. Estimation of fine aggregate content-- There are two standard methods to establish the fine aggregate content, the mass method and the volume method. We will use the "volume" method. "Volume" Method -- This method is the preferred method, as it is a

MoreOn the other hand coarse sand produces harsh and unworkable mix. Thus the fineness modulus of sand should not be less than 2.5 and more than 3.5 for producing good quality concrete. Observations: Fineness modulus for coarse aggregate = 746/100 = 7.46 . Fineness modulus for fine aggregate =
