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 given below.

[PDF]Get PriceThe fineness modulus is an empirical factor that gives a relative measure of the proportions of fine and coarse particles in an aggregate. It is a value widely used to indicate the relative fineness or coarseness of a fine aggregate.

Get PriceJul 20, 2018 · Generally speaking, the higher the fineness modulus, the higher the slump value — or in other words — the stiffer the concrete will be. Fineness modulus also provides important information about the density of the resulting concrete, as well as its compressive strength.

Get PriceTo characterize the overall coarseness or fineness of an aggregate, a concept of fineness modulus is developed. The Fineness Modulus is defined as. Fineness Modulus = Σ(Cumulative Retained ...

Get PriceFineness Modulus (FM) of concrete aggregates is an empirical figure representing the mean particle size of an aggregate sample. The number is required in the selection of proportions for the concrete mix design process, but its real influence is not always understood by users.

Get PriceFineness Modulus. It is the cumulative percentage retained on standard sieve 150μm or sieves No 100 and above divided by 100. It is a single factor or an empirical number which we get from the results of sieve analysis. The value of FM will not change if we add non standard sieves in standard set of sieves.

[PDF]Get Priceb) As per the grading given in Table 1, the fineness modulus of sand could vary from I.2 to 2.2. However, it is preferable to have minimum fineness modulus of l-4 in case of crushed stone sands and crushed gravel sands and a F. M of 1 5 in case of naturally occurring sands. Hence,

Fineness Modulus is an indication grading of particle size. More the value of FM more coarser the aggregate is. Now because density vary with particle size, and also the void spaces inside the concrete is a function of aggregate size, it is very important to have aggregate of all sizes in mix proportion for attaining good strength.

[PDF]Get PriceMedium sand: fineness modulus of 3.0–2.3, with an average particle size of 0.5–0.35 mm; 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.

[PDF]Get PriceFineness Modulus. Fineness Modulus is de! ned as an index to the particle size not to the gradation. Fineness Modulus is calculated from the sieve analysis. It is de! ned mathematically as the sum of the cumulative percentages retained on the standard sieves divided by 100.

Get PriceFineness modulus defines the size of the of the aggregates on concrete mix design. There area some limits on it though.

Get PriceLimits 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.

[PDF]Get PriceTherefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = 2.75. Fineness modulus of fine aggregate is 2.75. It means the average value of aggregate is in between the 2 nd sieve and 3 rd sieve. It means the average aggregate size is .
