Nov 03, 2017· 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.
The test done for finding the fineness of cement by sieving the cement on the standard IS sieve is called the fineness test of cement. The proportion of cement size greater than 90 microns is considered as fineness cement. In other words, the fineness of the cement is the particle size of cement. The maximum residue after the sieving in standard
Apr 12, 2020· What is the fineness of the cement? A Fineness of Cement is Measure of the size of Cement Particle, and it is described in terms of the specific surface area of Cement particle. The Fineness of cement can be Calculated by particle size analysis, by using the air permeability method, by using sedimentation method.
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).
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.

Appartus used for fineness test of cement is 90µm IS Sieve, Weight Balance having capacity 10mg to 100g, Nylon or pure bristle brush and sieve shaking machine (optional). Appartus used for fineness test of cement. Sieve method test procedure: Collect a sample of cement and rub with your hands. The Fineness test sample should be free of lumps.
Fineness of cement = (W2/W1) x 100. The test has to be done with at least three samples from the same batch. The average value is the fineness of the cement. The ratio between the test samples should not be greater than 0.2% if else then repeat the test. The retaining cement particles in sieve should not be more than 10%.
Nov 10, 2020· Fineness Test of Cement. February 2, 2018 October 3, 2018 by Kathir Leave a Comment. 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
Apr 06, 2018· Therefore finer cement reacts faster with water and the rate of development of strength and corresponding heat of hydration is high. Fineness test is used to check the proper grinding of cement and measures the surface area of the cement particles per unit mass.
Apr 06, 2018· Fineness test is used to check the proper grinding of cement and measures the surface area of the cement particles per unit mass. FINENESS LIMIT: It should not exceed following percentage by weight for different types of cement. Ordinary Portland cement =10%; hardening cement =5%; Low heat cement =5%
Test To Check Fineness Of Cement Procedure to determine fineness of cement i) Weigh approximately 10g of cement to the nearest 0.01g and place it on the sieve. ii) Agitate the sieve by swirling, planetary and linear movements, until no more fine material passes through it.
TESTS ON CEMENT 8.1 Fineness of Cement 8.1.1 Introduction. This simple test is not intended to indicate the true fineness of a cement as may be determined by apparatus for measuring the specific surface, but it is intended to give an indication of any hydration in the cement which has led to the formation of small pieces of hardened material.
introduction fineness test cement . Density of Cement Quantachrome Instruments. The density of cement should be known in connection with the design and control of concrete mixtur Fineness The permeameter most closely associated with the cement industry is the Blaine apparatus This method requires an operator to pack a bed of powder to 50%
Feb 28, 2015· FINENESS TEST 6. Free Powerpoint Templates Page 6 Fineness of cement is tested in two ways. • By sieving. • By determination specific surface by air permeability 7. Free Powerpoint Templates Page 7 • Take correctly 100grams of cement on a standard IS sieve No.9 • Break down the air-set lumps & sieve it &weigh it.
1. Fineness Test. Fineness is the mean size of cement grain. It is done to measure the mean size of cement grain. The finer the cement the surface area for hydration will be large and it increases the strength of cement. But the fineness varies in different types of cement. One of the Following three methods can be applied to test the fineness
