Blaine Air Permeability

This apparatus determines the fineness of Portland Cement and measures the specific surface area of fine materials in square centimeters per gram of test sample. By using this apparatus, a quantity of air is drawn through a bed of definite porosity. The rate of air flow is determined by the pore volume in the bed, a function of the size of particles.
