This test method is used to determine the grading of materials proposed for use as aggregates or being used as aggregates. Sieve Analysis; Accurate determination of materials finner than 75 micron (Sieve No 200) can not be achieved by this test; Related Theory: Fineness Modulus. It is the cumulative percentage retained on standard sieve 150μm ...
Standard methods of testing cement are essential adjunct to the cement specifications. This standard in different parts, lays down the test procedures to evaluate the physical properties of different types of hydraulic cement. This part covers determination of fineness of.cement by wet sieving.
Fineness Test of Cement. PROCEDURE OF FINENESS TEST OF CEMENT: Collect a sample of cement and rub with your hands. The Fineness test sample should be free of lumps. Take 100 gm of cement sample and note its weight as W1. Drop 100 gm of cement in 90 µm sieve .
The sieving method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling the production process. The air-jet sieving method measures the retention on sieving and is suitable for particles which substantially pass a 2,0 mm test sieve.
1.1 This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the 300-μm (No. 50), the .
It is used for specification purposes and for controlling reading and uniformity and it is also used in a computation method of proportioning concrete. Apparatus Required. 1) IS test sieve 10 mm, 4.75 mm, 2.63 mm, 1.18 mm, 600 Micron, 300 Micron, 150 Micron. 2) Sieve shaker. 3) Weighing Machine. READ MORE. Determination of Normal Consistency of ...
dry sieving method for the determination of the retention on sieving of particles which substantially pass a 2.0 mm test sieve. ASTM C430 [7] standard gives an alternative wet sieving method for the determination of fineness of hydraulic cement based on the retained material on the no. 325 sieve (45 lm opening size).
The procedures used for the fineness analysis of sub-sieve particles are: elutriation by means of air or water, sedimentation, hydrometer readings, and the obscuring of a beam of light by dilute suspensions of the particles. ...

May 01, 2020· To determine the number of cement particles larger than 90 µm. or Fineness test of cement. The following apparatus is used. 100g of cement (test sample), Weighing balance which can weight with an accuracy of 1mg, Standard Sieve of size 90 µm, Sieve pan with lid, Sieve Shaking Machine(optional)
Test Results and Discussion In this experiment, we are tasked to determine the fineness of the cement. We used type 1 Portland cement in this particular experiment. The apparatus that we used are sieve #200, weighing balance, sampling spoon, and mixing bowl. To determine the fineness of the cement, we have used the Sieve analysis method. A sieve analysis (or gradation test) is a practice or ...
12.2 Fineness Standard EN 196-6 describes two methods of determining the fineness of cement: sieving method air permeability method ( Blaine) 12.2.1 Sieving Method This method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling production process.
This part covers determination of fineness of cement by dry sieving. The second revision of this standard has been prepared with a view to align this test method with European S!andard EN 196 (Part 6) Method of testing cements: Determination of fineness.
per one gram of cement. Although determination of specific surface is more accurate to judge fineness of cement, it is rarely used except for specific purpose. In contrast sieving is most commonly usedmethod to determine fineness of cement and is quite good for field works.

IS 4031(Part 1):1996 Methods of Physical Tests for Hydraulic Cement: Determination of Fineness by Dry Sieving (second revision). Reaffirmed- May 2016 4. Procedure 1. Agitate the sample of cement to be tested by shaking for 2 min in a stoppered jar to disperse agglomerates.
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. The proportion of cement of which the grain sizes are larger than the specified mesh size is thus determined. Contents:Fineness Modulus [.]
Methods of testing cement - Part 6: Determination of fineness; German version EN 196-6:2010. This European Standard describes three methods of determining the fineness of cement. The sieving method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling the production process.

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.
Apr 12, 2020· 3 Particle size distribution method. Aim: To check the fineness of cement by particle size distribution method (Sieve Method). Apparatus: For (American Standards) 45 u (u = microns) sieve is used, For (Indian Standards) 90 u (u = microns) sieve is used, Pan, sieve cap and cement. Procedure: First, take the cement sample of 100 grams 'W1'
