.
The Blaine Air Permeability Apparatus determines the fineness of Portland cement in terms of the specific surface area expressed as the total surface area in square centimeters per gram of mortar or cement.
The Blaine works by drawing a definite quantity of air through a cement bed exhibiting a definitive porosity value.
The number and size of the pores in a prepared bed of definite porosity are a function of the particles’ size and determine the airflow rate through the bed.
