Magnesia cement
Magnesia cement (magnesia binder) - a kind of inorganic binder based on magnesium oxide, and shuts chloride or magnesium sulfate. The main advantages of magnesia cement - fast curing, high strength achieved, excellent adhesion to wood. Due to the unique properties of magnesium cement is used for everything monolithic screed, for the production мagnesium oxide wallboard, abrasive wheels, making partitions, stair treads and drip plates, facing tiles, insulation products.
