Jul 30 2016What Is Fineness Modulus of 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.

Fineness modulus of aggregate: It is the index number used to indicate the average size of particles in the aggregates. It can be empirically calculated by adding the cumulative percentage of sample of an aggregate retained on each of specified series of sieve, and dividing the sum by 100.
2 The larger the screen size, the larger the fineness modulus of artificial sand and the lower the stone powder content. On the contrary, the smaller the fineness modulus and the larger the content of stone powder. In the general sand making process, the recommended mesh is 3.5-4.5 mm.
If the Fineness Modulus (F.M) lies between 2.90 to 3.20, it is named as Coarse Sand. If the Fineness Modulus (F.M) lies between 2.60 to 2.90, it is called as Medium Sand. If the Fineness Modulus (F.M) lies between 2.20 to 2.60, it is defined as Fine Sand. On the Basis of Source: Depending upon the Source of Sand, it can be classified into three
Fineness modulus: The Fineness modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100. The fineness modulus of 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. The fineness modulus plays very important role in mix proportion .

Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus is the number at which the average size of particle is known when we counted from ...
the grading for both river sand and CCB are similar. Their grading can be described as uniform, and only a few sizes dominate the bulk material. This similarity is further reinforced from the values of their fineness modulli (see Table 2). Both the river sand and the CCB with the fineness modulus respectively of 2.88 and 2.44 satisfy ASTM C
Determination of Fineness Modulus of Sand To determine the fineness modulus, we need standard sieves, mechanical sieve shaker (optional), dry oven and digital weight scale. Sample preparation Take a sample of fine aggregate in pan and placed it in dry oven at a temperature of 100 – 110 o C. After drying take the sample and note down its weight.
The 28 days compressive strength according to fineness modulus of fine aggregate increased about 3 ma as the fineness modulus increased from 2.0 to 2,5, and 3.0. However, the 28 days compressive strength decreased about 9 ma at 3.5 fineness modulus as compared with 3.0 fineness modulus.
Fineness Modulus Of Manufactured Sand. range of fineness modulus of manufactured sand. IS 1542 1992 sand for plaster b As per the grading given in Table 1 the fineness modulus of sand could vary from I2 to 22 However it is preferable to have minimum fineness modulus of l-4 in case of crushed …
Natural sand was not available in the nearest localities and hence, except in the case of power house, crushed sand was used. For this purpose, eight crushing and screening plants were installed. As a trial and error, 10 to 20 per cent river sand was mixed with the crushed sand to bring the fineness modulus, but the improvement was not good enough.
Crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand. This dust is composed by particles which pass 75 μm BS sieve.

Jul 30 2016 · 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
Generally, when the sand is fine, smaller proportion of it is enough to get a cohesive mix; while coarser the sand, greater has to be its proportion with respect to coarse aggregate. River sand having density of and fineness Modulus (FM) of 2.51 was used. The specific gravity was found to be 2.47.
The fineness modulus of sand can be calculated to give the site engineer an idea of the overall fineness or coarseness of aggregates received at the site. Aggregate field test observation sheet Only sand with between FM 2.6 to 2.9 was considered suitable for nominal mix proportion.
Materials – Aggregate – Classes "Aggregate" is a collective term for the mineral materials such as sand, gravel … Rather than list WSDOT specifications for each test in their respective ….. common gradation description for fine aggregate is the fineness modulus. …. The amount of fines generated is measured and the result is reported as a degradation factor.
ABSTRACT: The main object of this study is to optimize the use of crushed sand from basalt aggregates and sand dune in hydraulic concrete. In this sense, we have studied a series of tests, of partial and/or total substitution of sand dune by crushed basalt sand…
This paper focuses on the modeling and optimization of the physical and mechanical properties of self-compacting concrete (SCC), prepared using the modified packing model design, taking into consideration sand's particle size distribution (PSD) and fineness modulus (FM). The optimization is predicated using the response surface methodology. The analysis of variance is exploited to …
Natural sand i.e. locally available River sand having a bulk density of 1.71 kg/m3 was used for the construction (specific gravity is 2.65). This sand has the Fineness modulus of 5.24. When the sand is wet, the water is in the sand, also affecting the total matter in the volume.

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 2.9 and 2.9 to 3.2 indicates that the sand is fine, medium and coarse confirming to grading zones ranging from IV to I (IS383). It has been verified and found, at various locations
