Aug 14, 2019· Fineness modulus of aggregate is an index number which gives an idea about the finance of aggregate and is an approximate proportion of the average size of particle in the aggregate. It is found out by sieve analysis test of standard size in the laboratory. The thumb rule is lower the fineness modulus, particles are smaller and higher the fineness modulus, particles are larger.
Jun 02, 2012· Degree of gradation is also called fineness modulus of sand. We find fineness modulus and compare it the standard recommended values. Apparatus: The apparatus consists of six different types of sieves i.e. #4, #8, #16, #30, #50, and #100 sieve. The smallest sieve number is at the top and the others are arranged in ascending order.

The fineness of the sand plays an important role in the finishability of the concrete mix, and even small changes in fineness can affect finishing. The fineness modulus is a single parameter that describes the grading curve and can be useful in checking the uniformity of grading.
River sand 2.507 Quarry dust 2.688 Coarse aggregate 2.703 3.2.3 Fineness Modulus Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 4.75mm to 150 microns and …
Sieve shown in pic below is not the actual 90µm seive.Its just for reference. Procedure to determine fineness of cement i) Weigh approximately 10g of cement to the nearest 0.01g and place it on the sieve. ii) Agitate the sieve by swirling, planetary and linear movements, until …
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:-
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. The fineness modulus number affects the workability and finish of concrete. Before calculating fineness modulus, lab technicians pour aggregate onto sieves. Fineness ...
Jan 28, 2018· 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.
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 […]

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.
Jul 20, 2018· Fineness modulus also provides important information about the density of the resulting concrete, as well as its compressive strength. Both of these factors must be taken into consideration when designing the concrete. For more information about the role played by fineness modulus, contact the concrete experts at Southport Concrete Corp.
Sep 01, 2014· 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 ...
Obviously, it is used for plastering work. The fineness modulus should not be more than 1.5 and silt content should not be more than 4% in this type of sand. Concrete Sand. For the concreting purpose, we generally use coarse sand. The fineness modulus of this sand should be 2.5 to 3.5 and it should not contain more than 4% silt. Based on Their ...
