Blaine Air Permeability Replacement U-Tube, Calibrated
Replacement Glass U-Tube for Blaine Air Permeability Apparatus.
Features:
- Attaches easily to a wooden panel of the manometer
- Calibrated
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.
