About This Product
The Blaine test shows how fine a cement is by measuring how easily air passes through a packed bed of the powder. Finer cement has more surface area per gram and slows the air more. A bed of known size is made in the permeability cell, air is drawn through it, and the time taken by the manometer liquid to move between marks is used to calculate the specific surface. Students use it to link fineness with the rate of strength gain of cement. The Blaine's Air Permeability Apparatus can be supplied and exported to buyers in Eritrea, Papua New Guinea, Cabo Verde, Jamaica and South Korea.
