18/06/2014 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 the cement particles per unit mass. Cements with finer particles have more ...

12.2.2 Air Permeability Method ( Blaine Method ) The fineness of cement is measured as specific surface. Specific surface is expressed as the total surface area in square metres of all the cement particles in one kilogram of cement. The higher the specific surface is, the finer cement will be.

The air permeability specific surface of a powder material is a single-parameter measurement of the fineness of the powder. The specific surface is derived from the resistance to flow of air (or some other gas) through a porous bed of the powder. The SI units are m 2 kg −1 ("mass specific surface") or m 2 m −3 ("volume specific surface").

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% porosity, +/- 0.5% using thumb pressure only. This means that the true density of the cement under test be known, except for Portland cement when a density of 3.15 g/cm 3 is assumed ...
