To find fineness modulus of coarse aggregate we need sieve sizes of 75mm 375mm 19mm 95mm 475mm 236mm 118mm 06mm 03mm and 015mm Fineness modulus is the number at which the average size of particle is known when...
Sieve analysis is used to calculate the fineness modulus of fine and coarse aggregates. Sieve analysis is an analytical technique used to determine the particle size distribution of a granular material with macroscopic granular sizes. The technique involves different layers of sieves with different grades of sieve opening sizes. The finest sized sieve lies on the bottom of the stack while each ...
Fineness Modulus of Fine Aggregate. Fine aggregates is the sand used in mortars. The size of the fine aggregate is limited to maximum beyond which it is known as coarse aggregates. Fineness modulus is only a numerical index of fineness that gives some idea about the mean size of the articles in the entire body of concrete.
Fineness modulus of coarse aggregate as per is code Yes n. 354 of 1949. Standard specifiions (coarse aggregates and fine from natural sources for concrete) Order, 1949. I, Daniel Morrissey, Minister of Industry and Commerce, in the exercise of power given to me by subsection (3) ...
Fineness Modulus of Aggregates The Inside Scoop. An example provided in the ACI 211 standard states that For a fine aggregate having a fineness modulus of 28 and a 375mm nominal maximum size of coarse aggregate the table indies that 071m3 of coarse aggregate on a dryrodded basis may be used in each cubic meter of concrete The required dry mass is therefore 071 x 1600 = 1 136kg...
· Fineness modulus gives us an overall idea whether the material is fine or coarse. It also indies the surface area of the particles. Lower the surface area of the aggregate, the required amount of fresh cement paste to cover the aggregate particles will be less and thus less water is required.
coarse aggregate. There are several reasons for specifying grading limits and nominal maximum aggregate size; they affect relative. 82. Design and Control of Concrete Mixtures EB001. Fig. 54. Range of particle sizes found in aggregate for use in concrete. (8985) Fig. 55. Making a sieve analysis test of coarse aggregate in a laboratory. (30175 ...
2 Fineness Modulus % 3 Water absorption % COARSE AGGREGATE: Crushed aggregate confirming to IS: was used. Aggregate of size 12mm of specific gravity and fineness modulus are shown in. Table 3: Properties of coarse aggregate PROPERTY RESULT 1 Specific Gravity 2 Fineness Modulus %
3. Coarse Aggregates After the material has been sieved, remove each tray, weigh each size, and record each weight to the nearest g. Be sure to remove any aggregate trapped within the sieve openings by gently working from either or both sides with a trowel or piece of flat metal until the aggregate is freed. Banging the sieve on the floor or
7/30/2016 · Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. 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 fine aggregate .
Fineness Modulus of Coarse Aggregate. Open fineness modulus of coarse aggregate experiment, a window will appear as shown. Hower pointer over description to read basic definitions then click on NEXT Button at the bottom right corner. Click on ON Button to switch on the weighing machine. Move the mouse pointer to place tray on on the weighing ...
The information obtained from fineness modulus is helpful in the following ways; Sieve Analysis. 1 Fineness modulus tells us directly whether the material is wellgraded or gapgraded. 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.

Sieve Analysis of Coarse Aggregate: From the Field to the Lab. In Part 2 of this 3part series, we addressed how to properly prepare bulk field samples for testing in the lab, necessary equipment, and helpful tips. Now that you understand how to perform all the prework on samples prior to testing, we'll cover test procedures for effective ...
Sieve Analysis Calculation. Fineness modulus belongs to the number to specify the average size of particle while counting them from lower order sieve size to higher order sieve Therefore, while measuring coarse aggregate, all sizes of sieves are necessary Link for Download Excel sheet for sieve analysis of aggregate and to calculate fineness modulus.
· The fineness modulus of Fine Aggregate is For a good fine aggregate, the FM should be between and (ASTM Range for fine aggregates).Our result lie in this range as the graph shows that our sample is lies b/w maximum and minimum cumulative percentage passing.
information obtained from fineness modulus is helpful in the following ways; Sieve Analysis 1 Fineness modulus tells us directly whether the material is wellgraded or gapgraded. 2 Fineness modulus gives us an overall idea whether the material is fine or coarse. Higher the value of .
