The size of the particles of the cement is its fineness.The required fineness of good cement is achieved through grinding the clinker in the last step of cement production process.As hydration rate of cement is directly related to the cement particle size, fineness of cement is very important.
FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement whose grain size is larger then specified mesh size.
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 [.]
Procedure to determine fineness of cement by dry sieving method: Take the 100 gm of cement sample given using balance as initial weight as W1 gm. Take 90 micron IS sieve and keep pan at bottom. Place the measured 100 gm cement sample on 90 micron sieve and break the visible lumps present in cement using figures without pressing it on sieve.
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 ...
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 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 air-entrained concrete to deterioration ...
To Determine The Fineness Of Cement By Dry Sieving Theory: Cement is obtained by granding the various row material. The degree to which the cement is drawn to smaller and smaller particals is called fineness of cement. Finer the cement higher the rate of radiation and do faster the development of strain. This is because finer cement .
Apr 06, 2018· WHAT IS FINENESS OF CEMENT? Fineness of cement is property of cement that indicate particle size of cement and specific surface area. and indirectly effect heat of hydration. IMPORTANCE/EFFECT OF FINENESS OF CEMENT: Fineness of cement affects hydration rate hence the rate of strength gain. The smaller the particle size, the greater the surface area-to-volume.
Nov 03, 2017· Fineness test of cement using sieve analysis this. Excessive fineness makes cement to shrink and increases the setting time. ... Fineness test of Cement and its Significance. Krishna November 3, 2017 STRUCTURE 12 Comments. Fineness of Cement is measured by sieving cement on standard sieve. ... Important Topics.
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 ...
Aug 08, 2017· There are different types of sieves such as # 10, # 100,# 200,# 300 etc. 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 the following sieve numbers are recommended by ASTM. Cement by wet process = # 300 sieve Cement by dry process = # 200 sieve 3.
IS 4031 (Part 1) : 1996 Indian Standard METHOD OF PHYSICAL TESTS F
Test to Check Fineness of Cement. 2014923&ensp·&enspTest to Check Fineness of Cement FINENESS so we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement whose grain size is larger than specified mesh size.
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.

To Test the Fineness of Cement By Sieve Analysis Method (Dry Method) DEPARTMENT OF CIVIL ENGINEERING
Oct 03, 2018· To determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996. Principle. The fineness of cement is measured by sieving it through a standard sieve. The proportion of cement, the grain sizes of which, is larger than the specified mesh size is thus determined. Apparatus. i) 90μm IS Sieve.
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 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.
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
