Blaine Air Permeability Apparatus

Blaine Air Permeability Apparatus determines the fineness of Portland Cement by measuring the specific surface area of fine materials in square centimeters per gram of test sample. A quantity of air is drawn through a bed of definite porosity, and the rate of airflow is determined by the pore volume in the bed, a function of the size of particles.

The components of the apparatus are a stainless steel test cell, plunger, perforated disc, calibrated U-tube manometer, and rubber aspirator and bulb, all mounted on a sturdy wood panel with a base. An 8oz bottle of red spirit manometer fluid, a package of filter paper, and a woodblock for holding the cell during filling are also included.

NIST Portland Cement #46h is required by ASTM and AASHTO standards for the calibration of the apparatus.
