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.
