3.7 The fineness and particle size distribution of Portland cement. The final step in the production of cement is to grind the clinker pellets (and added gypsum) into a fine powder. The resulting individual cement particles have a variety of angular shapes, and a wide range of sizes (see Figure 3-7 below).

Get PriceF. Fineness Modulus of Aggregate The Fineness Modulus (F.M.) of an aggregate is a numerical index of the relative fineness or coarseness of the aggregate. It is based on th e summation of the percentages of material passing the fineness modulus sieves and is determined by dividing this result by 100, and subtracting from 10.

Get PriceFineness 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 ...

Fine aggregate shall meet the requirements of Table 2. 1002.05.03 Coarse Aggregate

Get PriceThe information obtained from fineness modulus is helpful in the following ways; Sieve Analysis. 1- Fineness modulus tells us directly whether the material is well-graded or gap-graded. 2- Fineness modulus gives us an overall idea whether the material is fine or coarse. Higher the value of FM,coarser will be the aggregate.

Aug 31, 2019 · Some Civil Engineering Field Questions Answers What is the FM(Fineness Modulus)? Answer: FM( Fineness Modulus is an empirical figure obtained by summing up the cumulative percentage of materials retained on each of the sieve excluding 0.075 mm sieve and dividing the sum by .

Get PriceFM is the sum of the total percentages retained on each specified sieve divided by 100. ASTM C 33 requires the FM of fine aggregate to be between 2.3 and 3.1. The higher the FM, the coarser the aggregate. Fine aggregate affects many concrete prope...

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,

Get PriceThus the object in this paper is to find the best fineness modulus of sand to get the optimum grading of combined aggregate (all-in-aggregate), which is most suitable, and for economy. In general, the grading of aggregates, which do not have a deficiency or excess of any size of aggregate and give a smooth grading curve, produce the most ...

Get PriceCHAPTER 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.

[PDF]Get PriceMay 02, 2013 · Overview Fineness of cement is measured by sieving it on standard sieve. The proportion of cement of which the grain sizes are larger than the specified mesh size is thus determined. Apparatus Measuring Instruments NAME CAPACITY / RANGE / SIZE ACCURACY / LEAST COUNT Sieve 90 micron mesh — Balance 10g (max.) 10 mg Supplementary accessories [.]

Get PriceJun 02, 2012 · Degree of gradation is also called fineness modulus of sand. We find fineness modulus and compare it the standard recommended values. Apparatus: The apparatus consists of six different types of sieves i.e. #4, #8, #16, #30, #50, and #100 sieve. The smallest sieve number is at the top and the others are arranged in ascending order.

[PDF]Get PriceFINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement whose grain size is larger then specified mesh size.
