Blain Air Permeability Apparatus

Blain Air Permeability Apparatus

The Blaine air permeability apparatus is used to determine the fineness of Portland cement in terms of the specific surface expressed as total surface area in square centimeters per gram of cement. The Blaine apparatus draws a defined volume of air through a prepared bed of cement of defined porosity.

The apparatus comprises one each of Brass or stainless steel permeability cell 12.5mm,’U’ tube manometer with stop cock mounted on a laminated wooden stand, perforated metal disc, plunger, Rubber stopper, Rubber tube – 30cm long with rubber bulb.
