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.

Nov 01, 1996· In the cement industry the usual method of surface area determination is the so-called Blaine method. This method measures the time for a specific volume of air to flow through a known volume of compacted powder and together with the density of the substance, this is used to calculate the specific surface area of the sample.
