2020-11-13 Why is fineness test of cement done? The fineness test of cement is done for: 1) Proper grinding of cement. Finer cement has the quicker action with water and get early strength. 2) Increasing surface area: Finer the cement more surface area is covered by it. 3) Reducing bleeding: Bleeding can be reduced by increasing the fineness of cement but it can lead to shrinkage as we have to increase the

2017-11-3 Procedure for finding Fineness test of cement: Take a sample of cement and rub the cement with your hands. The test sample should be free of lumps. Now Take 100g of cement and note it as W1. Pour 100g of cement in 90 µm sieve and close it with the lid. Now place the sieve in Sieve shaking machine for two minutes.

2020-11-15 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).

2018-2-2 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

Test To Check Fineness Of Cement. 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.

Fineness Test on Cement is carried out to check proper grinding of cement. Fineness of cement particles may be determined either by sieve test or by permeability apparatus test. In sieve test, the cement weighing 100 gm is taken and it is continuously passed for 15 minutes through standard BIS sieve no. 9.

Fineness test of cement is a simple test that involves the determination of the fineness of the cement simply by sieving the cement. In general, the test includes determination of the weight of the cement particles whose size is greater than 90 microns and thus the percentage retained is computed.

2020-11-9 Test Procedure. A quantity of 100g cement should be taken and weighed as W1. The sample cement should be free from lumps. Nicely stir the cement with a clean rod to spread the fineness to the whole area. Now place the cement sample into the 90-micron sieve and close it by the lid. Then shake the sieve gently for at least 15 minutes.

2017-10-17 AIM: 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: 1) 90μm IS Sieve 2)

2020-10-11 A filter paper disc is placed on the top of the cement and the cement is compressed with the plunger till the plunger collar is in contact with the top of the cell. The plunger is then removed slowly. For each determination fresh filter paper disc should be used. Permeability Test: The permeability cell is attached to the manometer.

2. Increasing the fineness of cement from 2700 to about 4000 cm2/g reduces the water requirement of concrete. Increasing the fineness of cement beyond an optimum limit increases the water requirement of concrete. 3. The workability of non air-entrained concrete is increased by increasing the cement fineness.

Fineness is tells about the particle distribution of cement. Fineness of is cement expressed in terms of total surface area of unit weight of of cement.
