Apr 07, 2020· Fineness of Cement. One of the last steps in the manufacture of cement is the grinding of clinker mixed with gypsum. Because hydration starts at the surface of the cement particles, it is the total surface area of cement that represents the material available for hydration. Thus, the rate of hydration depends on the fineness of the.
1.1 This test method covers the determination of the fineness of hydraulic cement by means of air jet sieving using a 45-µm (No. 325) sieve by Air Jet sieving.
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).
Fineness test of cement is done to determine the particle size of cement. As, the rule of thumb, the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good. The fineness of cement is determined by two methods; 1. Sieving Method. 2. Air Permeability Method (Blaine Method).get ...
Procedure to Determine Fineness of Cement. Stir the sample of cement to be tested by shaking for 2 minutes in a stoppered jar to disperse lumps. Stir the resulting powder gently using a clean dry rod in order to distribute the fines throughout the cement. Attach a pan under the sieve to collect the cement passing the sieve.
Testing Of Cement: Physical Tests (IS: 4031) Fineness Test . The degree of fineness of cement is the measure of the mean size of the grains in it. There are three methods for testing fineness: the sieve method-using 90 micron (9 No.) sieve, the air permeability method-Nurse and Blains method and the sedimentation method-Wagner turbidimeter method.
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 …
Jan 30, 2018· Laboratory test of cement There are two method of testing fineness of cement; Sieving method Air permeability method (Blaine) Sieving method In this method dry sieving is used, the principle of this is that we determine the proportion of cement whose grain size is larger then specified sieve size. ... (V2-V1) NOTE: (i) Duplicate determination ...
There are two methods of testing of fineness of cement. By sieving; By determination of the specific surface area; Following standards and methods are more commonly used when testing of fineness of the cement. AASHTO T 98 and ASTM C 115: Fineness of Portland cement by the Turbidimeter.
It is the English language version of EN 196-6 : 1989 and was drawn up by CEN Technical Committee 51, Cement and building limes. In it, two methods for determining the fineness of cement are described: (10 the sieving method: and (2) the air permeability method (Blaine). These methods are applicable to all the cements defined in ENV 197.
Conclusion After the experiment, our group was able to determine the fineness of the cement by sieve method. Based on our results, we have observed that sieving process should be done properly and carefully. In our data, the average fineness of the fineness of the cement is 97.62% which means it passed the standard because it is clearly not less than 78%.
