Re: Blaine value vs position parameter. Most often, today, particle size distributions (PSD) are measured by laser diffraction. All suppliers also calculate a specific surface from this PSD. This calculation includes a "shape factor" to take the shape of the particles into account.
The Blaine works by drawing a definite quantity of air through of bed of cement exhibiting a definitive porosity value. The number and size of the pores in a prepared bed of definite porosity is a function of the size of the particles and determines the rate of airflow through the bed.

HMK-C1 Blaine Apparatus is a cement testing apparatus used to determine the particle size of portland cement, limes and similar powders using the Blaine air-permeability method. It gives accurate and repeatable test results of cement specific surface area.
Despite the availability of instrumental methods of measuring particle size distributions, the classical method of air permeametry remains. The density of cement should be known in connection with the design and control of concrete mixtures. Fineness The permeameter most closely associated with the cement industry is the Blaine apparatus.
