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. The Blaine works by drawing a definite quantity of air through of bed of cement exhibiting a definitive porosity value.
The Blaine apparatus is a system that is used to determine the particle size of Portland cement, limes and similar powders. The Blaine value is expressed in terms of their specific surface area. The specified surface is determined by measuring the flow of resistivity of air through a porous bed of the dry cement powder. Read More...
