Blaine Air Permeability Apparatus
Product Details:
Blaine Air Permeability Apparatus is used for determining the fineness of cement in terms of specific surface expressed as total surface area in square centimeters per gram of cement. This is a variable flow type air permeameter. The apparatus consists one each of permeability cell 12.5mm I.D., Manometer 'U' type mounted on stand with a built in stop cock, Perforated disc, Plunger Rubber stopper, Rubber tube 30cm long. Packet of 12 filter paper discs and a bottle of 100cc dibutyiphthalate liquid.
Features:
Fineness of cement has a great effect on the rate of hydration and hence the rate of gain of strength.
Fineness of cement increases the rate of evolution of heat.
Finer cement offers a great surface area for hydration and hence faster the development of strength.
