• The Blaine Air-Permeability Apparatus is designed to determine the fineness of hydraulic cement by measuring its specific surface area, expressed in square centimeters per gram or square meters per kilogram.
• The apparatus operates by drawing a defined volume of air through a compacted bed of cement with a specified porosity. The resistance to airflow is measured to calculate the specific surface area, providing an indication of the cement’s fineness.
• Constructed with high-quality materials, including a stainless permeability cell and plunger, the apparatus ensures durability and consistent performance in laboratory environments.
• The inclusion of a U-tube glass manometer with a valve allows for precise measurement of pressure differentials during testing, enhancing the accuracy of results.
• The apparatus is supplied with essential accessories, such as filter papers, manometer liquid, and a rubber aspirator bulb, facilitating immediate use upon setup.
