Jan 01, 1994· The Importance of Fineness Modulus. 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 ...
Fineness Modulus of grading of aggregate. Fineness modulus is an empirical factor computed from the sieve analysis. It is defined as the sum of the cumulative percentages retained on the sieves of the standard series ranging from 80mm to 150microns and dividing the sum by 100. When all particles in a sample are coarser then say 600µm, the ...
It is pointed out that manufactured sand is anytime better than river sand. The particle shape is cubical, which is almost closer to rounded river sand. Another issue associated with river sand is that of obtaining required grading with a fineness modulus (FM) of 2.4 to 3.1. Generally FM of 2.2 to 2.6, 2.6 to
SB3 sand (FM=3.1) and SG5 sand (FM=2.2) were mixed to vary the fineness modulus from 2.2 to 3 and the compressive strengths of each corresponding mortar specimen determined after 28 days.
They are not as complex as natural sand. 6. Fineness Modulus. For natural sand, one kind of fineness modulus can be graded in many ways. The fineness modulus of machine-made sand can be controlled artificially by production process, and the production can be organized according to user's requirements, which is impossible for natural sand.
manufactured sand (M-sand) instead of natural river sand in making concrete. M-sand is obtained by crushing the natural granite stone in the vertical shaft Impact crushers and screening the output form the fine aggregates of size less than 4.75mm. Some studies has been reported the effect of M-sand on strength and durability properties of
May 24, 2020· What is Sieve Analysis and Fineness Modulus..? May 26, 2020. May 24, 2020 by admin. Sieve analysis is conducted to analyses the particle size distribution of the aggregates in a given sample. In general the aggregates used for making concrete are normally as of sizes ranges from 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 600 microns, and 150 microns.
Sep 01, 2014· 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. Type of Sand. Fineness Modulus Range. Fine Sand.
An 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. The required dry mass is, therefore, 0.71 x 1600 = 1,136kg."
Manufactured Sand (M-Sand): Manufactured sand confirming to Zone – II as per IS: 383-1970 is used. It was tested as per Indian standard specification. Table - 4.4 Detailed Description of Test on Manufactured Sand Physical Properties Manufactured Sand result Specific Gravity 2.5 Fineness modulus 2.75 Water Absorption 0.26%
In manufactured sand with well-designed screening system the general, the demand of natural river sand is quite high in required grading and fineness modulus (2.4 to 3.1) can be developing countries to satisfy the rapid infrastructure growth, achieved consistently .
Jul 20, 2018· To determine the fineness modulus, the contractor adds the cumulative percentage-retained values and divides the sum by 100. This process must be repeated for both coarse and fine aggregate sizes. Once the fineness modulus of each size has been determined, they can be combined by means of a special equation to determine the proportions ...
Effect of fineness of sand on the cost and properties of concrete Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Effect of fineness of sand on the cost and properties of concrete, quarry, aggregate, and different kinds of minerals.
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, …
The properties of sand, specifically the gradation and fineness modulus of sand, are among the principal factors known to affect the performance of both fresh and hardened concrete [8, 9 ...
The average value of fineness modulus is found. The zoning of aggregate as per IS: 2386(PART III): 1963 is found. The test results are given in table 5 for natural sand and table 6 for manufactured sand. Respective graphs for natural sand and manufactured sand is shown in fig2 and fig 3. Table - 5 Sieve analysis of Natural Sand Seive Size (mm)
range of fineness modulus of manufactured sand 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
Apr 17, 2015· On the other hand course sand produces a concrete mixture that is harsh and difficult to finish and will cause segregation.Therefore recommended FM range is 2.3 to 3.1. Following table shows fineness modulus for different types of sand
