Now a day’s fineness is usually measured by the Blaine air-permeability test that indirectly measures the surface area of the cement particles per unit mass. Cements with finer particles have more surface area in m 2 per . Sieve analysis (by dry sieving) measures the cement particle size whereas air permeability method and sedimentation method measures specific surface area of cement. Here we have explained the one method fineness of .

The principle behind air permeability method on cement is in "observing the time taken for a fixed quantity of air to flow through a compacted cement bed of specified .Permeability Test on Concrete 1. Three specimen of concrete each of 200mm dia and 120mm height are cast. 2. After 24 hours, the middle portion of 100mm dia is roughened and the remaining portion is sealed with cement paste. 3. .ρ density of cement [g.cm-3] η the viscosity of air at the test temperature taken from Tab.:27 The apparatus constant is determinate by measuring permeability of reference cement of known specific surface. The procedure repeats three times for three samples of cement bed. For eachSo it is necessary to check the permeability of concrete. To check the permeability of concrete, there are various methods. Some of them are most commonly used. They are as follows: Rapid Chloride Permeability Test. (RCPT) Water permeability test by pressure. Rapid Chloride Permeability Test (RCPT) The rapid chloride permeability test is a test .
