Sep 01, 2014· What is Fineness Modulus of Aggregate? Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100. Why to Determine Fineness Modulus? Fineness modulus is generally used to get an idea of [.]
The size of the particles of the cement is its required fineness of good cement is achieved through grinding the clinker in the last step of cement production hydration rate of cement is directly related to the cement particle size, fineness of cement is very important.
The number of the sieve indicates the number of holed present in a linear inch of that sieve. For finding the fineness of Wet or Dry cement, following number sieve is recommended by ASTM. Cement by wet process = # 300 sieve. Cement by dry process = # 200 sieve. Apparatus: Sieve # 200. Sample of cement. Triple beam balance. Brittle brush. Empty ...
Jan 28, 2019· The fineness of cement is a measure of the size of particles of cement and is expressed in terms of specific surface area of cement. Fineness can be calculated from ...
Fineness of Cement by Dry Sieving (Very Simple Procedure) To find fineness of cement by dry sieving method. In this method the cement sample is sieved dry on IS sieve no. 9. The residue left is expressed as percent of weight of sample, and in an indirect measure of fineness of cement.
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.
Methods of finding fineness of cement: Fineness of cement is found by two methods A) By method of dry sieving B) By specific surface method finding fineness of cement using Blanine''s air permeability apparatus. Though method B is more accurate it is rarely used for specific A is quite good for field work.
The Fineness test of cement is done by sieving cement sample through standard IS sieve. The weight cement particle whose size greater than 90 microns is determined and the percentage of retained cement particle are calculated. This is known as Fineness of cement.

Jan 29, 2019· The fineness of cement is a measure of the size of particles of cement and is expressed in terms of specific surface area of cement. Fineness can be calculated from ...
What is the mesh number of 90 micron sieve used for the fineness of cement? kindly tell me the mesh number of 90 micron sieve used for the cement as i needed it to pass marble powder through it Cement
FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – principle of this is that we determine the proportion of cement whose grain size is larger then specified mesh size.
The fineness of cement is determined by two methods; 1. Sieving Method. 2. Air Permeability Method (Blaine Method). However, in this article, we''ll only discuss about the sieving method of determining the Fineness of Cement. Because this is the most common and easiest method to test fineness of cement.

Fineness Modulus of Cement by Dry Sieving The Fineness modulus of cement 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.
FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – principle of this is that we determine the proportion of cement whose grain size is larger then specified mesh size.
Along with defining the importance of water/cement ratio and developing the slump test, he defined fineness modulus in 1918 as a way of characterizing concrete aggregates, simplifying the gradation curve and estimating the correct proportions to use in mix designs.
5. Check the sieve after every 100 sieving as per para of IS: 4031 (Part 1) 5. Observation 1. The fineness of a given sample of cement is _ _ _ _ % 2. Report the value of R, to the nearest percent, as the residue on the 90 micron sieve for the cement tested.
The value will change over time if the cement is exposed to various weather conditions. So it is essential to determine the specific gravity of cement before using it. This is why we are insisted on avoiding old stock cement, which may be affected by the external moisture content. The significance of specific gravity of cement

Sep 26, 2018· Fineness Modulus of Cement by Dry Sieving [ad_1] The Fineness modulus of cement 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.
Aug 13, 2019· Fineness of cement is property of cement that indicate particle size of cement and specific surface area. and indirectly effect heat of hydration. Significance of the fineness of cement? * Fineness of cement affects hydration rate hence the rate o...
The fineness of cement influences the drying shrinkage of concrete. When the water content is increased because of fineness, the drying shrinkage is increased. However, if excessive bleeding due to coarseness of the cement takes place, a reduction in the drying shrinkage occurs. 8. The resistance of airentrained concrete to deterioration ...
Sep 10, 2017· This test is determine the fineness of cement samples by dry sieving. Fineness of cement Fineness of Cement. It is the measure of total surface area of finer cements,surface area will be influences the rate of hydration, rate of strength, rate of strength development, shrinkage, cracking, bleeding and also the cost of cement.
