Fineness modulus of fine aggregate varies from to Fine aggregate having fineness modulus more than should not considered as fine aggregate. Various values of fineness modulus for different sands are detailed below. Type of sand Fineness modulus range Fine sand – Medium sand – Coarse sand –
· Fineness 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 modulus.
Effect of fineness modulus of manufactured sand on fresh. Effect of fineness modulus of manufactured sand on fresh properties of selfcompacting concrete D. Pavan Kumar and C. Sashidhar Selfcompacting concrete (SCC) is considered as an innovative construction material in the construction industry due to its excellent fresh and hardened properties.
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. Determination of fineness modulus is considered as a method of standardization of grading of aggregate the main object of finding fineness modulus is to grade the given aggregate for the most economical mix and workability with minimum quantity of ...
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)

1 y. ·. fineness modulus is necessary because sand should be coarse enough as well it should not be to fine like silt . It is important pack very closely to improve the density and the strength FM test is very important must follow. 504 views. ·.
highest values of fineness modulus are used instead of those with lowest values of fineness modulus. In Table 2, the fineness modulii of fine aggregate has been taken as ( fine sand ) for leaner mixes and ( coarse sand ) for richer mixes, for computing the constants.
The fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. 1. Grading. The fine aggregate shall not pass 45% from a single sieve and retained on the next consecutive sieve as shown in table1. The fineness modulus of the .
Fine sand fineness modulus of, with an average particle diameter 0 350 25 mm special fine sand fineness modulus of, with an average particle diameter of mm or larger the fineness modulus is, the coarser the sand will appropriate range of fineness modulus of the sand aggregate used in normal.
FINENESS MODULUS OF FINE AGGREGATE. FINENESS MODULUS OF FINE AGGREGATE TxDOT Designation: Tex402A Effective Date: August 1999 1. SCOPE This method determines the fineness modulus of concrete fine aggregate used in evaluation of natural and manufactured sands for portland cement concrete. The values given in parentheses (if provided) are not standard and may not be .
Types of Sand Classifiion of Sand. Followings are the classifiion of Sand: Based on the grain size of the particle, sand is classified as Fine Sand( to ), Medium Sand( to 2mm), and Coarse Sand( mm to ) Based on origin, sand is classified as Pit sand, River sand, Sea sand, and manufactured sand.
Therefore, fineness modulus cannot be used as a description of the grading of aggregate. When the use of the fineness modulus in the assessment of variations from the same source or parabolic behavior of a concrete mix is of great help. It reduces the ambiguity in the classifiion of fineness of sand.
Fineness Modulus of Sand. Fineness Modulus of Sand Download as PDF File (pdf), Text File (txt) or read, When developing a mixture proportions for concrete, the FM of the sand would be, of Concrete With Natural and Manufactured Sand in Residential Building.
SB3 sand (FM=) and SG5 sand (FM=) were mixed to vary the fineness modulus from to 3 and the compressive strengths of each corresponding mortar specimen determined after 28 days.
The fineness modulus of aggregate is simply a measurement of the average size of the aggregate. It can be calculated with the help of different sizes of the sieve. Now, let us see some numerical Examples to calculate the fineness modulus of aggregate.
modulus of river sand is Manufactured Sand: MSand was used as partial replacement of fine aggregate. The bulk density of Manufactured sand was kg/m3, specific gravity and fineness modulus was found to be and, respectively. The percentage of particles passing
· What Is Fineness Modulus of Sand Civil Lead. Fineness modulus = (Summation of cumulative of weight retained up to 150 microns) / 100. Fineness modulus = 240/100. Fineness modulus = So in our case it is Fine Sand. Value of fineness Modulus of Sand. Read More; An Investigation into the Use of Manufactured Sand as a . Jun 02 2016 · At w/c ...
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,, .
· What is Fineness Modulus .?? Fineness modulus are ready index of coarseness or fineness of the material. It is also defined as an empirical factor obtained by adding the cumulative percentage of aggregate retained on each of the standard sieves ranging from 80mm to 150micron and dividing the sum by an arbitrary number 100.
