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 steel 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.
