In this study, the factors affecting the density and specific surface area (Blaine value) of coal fly ash were investigated on the basis of experimental results obtained using our combustion test facility and the ash data from the boiler of an actual electric power plant.

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.

The Blaine Air Permeability Apparatus determines the fineness of Portland cement in terms of specific surface area expressed as the total surface area in square centimeters per gram of mortar or cement.

When the surface area of a cement is measured using gas sorption, a technique that measures how many gas molecules can fit on the surface of a solid, the resulting value is 2-3 times higher than the Blaine value . This occurs because the cement particles have a rough, irregular surface with internal cracks and pores.

The reference material is always the cement which the Blaine specific surface and density are knew. These parameters will be used to determine de K of your Blaine apparatus.

Ordinary Portland Cement. The most versatile cement product used for a wide range of applications, including general civil engineering and construction works, smaller works and plastering mortar.

The fineness of cement is a property that must be carefully controlled during the manufacturing process. The total specific surface of the cement represents the surface area available for hydration. Various methods are in use to measure the specific surface of cements.

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").

Re: Blaine value vs position parameter. The Rosin Rammler distribution has nothing to do with surface area. It is determined by converting two sieve residues into the Rosin-Rammler particle size distribution.
