fineness of cement test

To determine thefineness of cementby dry sieving as per IS: 4031 (Part 1) – 1996. Principle. Thefineness of cementis measured by sieving it through a standard sieve. The proportion ofcement, the grain sizes of which, is larger than the specified mesh size is thus determined. Apparatus. i) …

Procedure to determinefineness of cementi) Weigh approximately10gofcementto 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.

The size of the particles of thecementis itsfineness. The requiredfinenessof goodcementis achieved through grinding the clinker in the last step ofcementproduction process. As hydration rate ofcementis directly related to thecementparticle size,fineness of cementis …

Cement:Fineness TestThe degree offinenessofcementis the measure of the mean size of the grains in it There are three methods for testingfineness: the sieve methodusing 90 micron 9 No sieve, the air permeability method Nurse and Blains method and the sedimentation method.

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.

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.

Jun 18, 2014· In the early 1900s, cement fineness was expressed as the mass of cement per fractional size (percent weight retained on specific sieve sizes). Now a day’s fineness is usually measured by the Blaine air-permeability test that indirectly measures the surface area of …

Fineness test of cementis a simpletestthat involves the determination of thefinenessof thecementsimply by sieving thecement. In general, thetestincludes determination of the weight of thecementparticles whose size is greater than 90 microns and thus the percentage retained is computed.

Fineness testis used to check the proper grindingof cementand measures the surface area of thecementparticles per unit mass.FINENESSLIMIT: It should not exceed the following percentage by weight for different typesof cement. Ordinary Portlandcement=10%; Rapid hardeningcement=5%; Low heatcement=5% ←

1.1 Thistestmethod covers determination of thefinenessof hydrauliccement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square metres per kilogram,of cement.
