Blaine Apparatus Air Permeability Tests can be done by any one of Torontech's Blaine test apparatus. We have several options to choose from included an automatic air permeability test apparatus, a manual air permeability test apparatus, a PC-controlled air permeability test apparatus. The Blaine air permeability tester is mainly used to measure the fineness of the cement,
The air permeability specific surface of a powder material is a single-parameter measurement of the fineness of the powder. The specific surface is derived from the resistance to flow of air (or some other gas) through a porous bed of the powder. The SI units are m 2 ·kg −1 ("mass specific surface") or m 2 ·m −3 ("volume specific surface").
Did You Know? A concrete contractor is a professional who places, colors, finishes, repairs, and maintains concrete, whether for interior, exterior, residential, or commercial use. Many homeowners use contractors for projects like driveways, pools, and patios. Concrete is a durable, sustainable substance that can be colored, shaped, and stamped into almost any design.
