The appropriate range of fineness modulus of the sand aggregate used in normal concrete is 3.7–1.6. Both medium sand and coarse sand spiked with some fine sand (coarse:fine = 4:1) are applicable. Sand aggregate plays a significant role as a skeleton and in passing the stress in concrete.

Sometime it may happen that, the aggregate available at site is not conforming to the desired grading. In such case two or more aggregates from different sources may be combined to get the required grading. Fineness modulus value can be used as a technical way to blend coarse aggregate with fine aggregate to produce desired […]

Workability of mix is also fixed in range of 45 to 55 mm slump. Since mix with so different fineness modulus of sand, will result in different water demands, so watercement ratio is kept constant and to adjust workability slight adjustments in admixture dosages has been made.

Fineness of fine aggregate is related to term fineness modulus; most commonly sand. Fineness modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete. ... Here we will discuss about ranges of fineness modulus of sand according to different standard.

Nov 21, 2017· Irrespective of type of sand. A good sand which is used in construction should have less than 3% of Silica and no organic impurities. Different construction activities requires different fineness modulus of sand. Sand used in Brick work:-The sand used for Brickwork should have a fineness modulus of 1.2 to 1.5. Sand used in plastering:-

Finess Modulus is just a value (number) indicating the fineness or coarseness of the aggregate. So, a river sand (natural sand) will be in the range of2.5 or so to 2.7 and P-gravel (P-stone, Birds ...

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.

4.5.9 Fineness Modulus • Fineness modulus is the sum of the cumulative percentage retained on the sieves of the standard test sieves. Fineness modulus (FM) = (Cum. percent retained / 100) Standard test sieves are as follows: Coarse aggregate: 75mm, 38mm, 20mm, 10mm Fine aggregate: 4.75mm, 2.36mm, 1.18mm, 0.600mm, 0.300mm, 0.150mm Total 54 41

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).

Jun 05, 2016· Fineness Modulus of Sand WHY TO DETERMINE FINENESS MODULUS? 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 ...

The application of fineness modulus and particle size distribution of aggregate is to fine the aggregate is coarse or fine wheather it can be used in making mortar or concrete. If not what corrective action as to be taken is decided upon. Then the particles distribution study given an idea as to weather the material well grade or not.

Fineness modulus estimates the proportions of aggregate in construction materials. Aggregate is inert granular material such as sand, gravel or crushed stone used to form concrete.
