Description of Alkali-resistant Brick:
With the characteristics of high strength, good volume stability and good alkali corrosion resistance, alkali-resistant brick reacts with alkali to form a high-viscosity glass phase to prevent the penetration of alkaline slag during use. Alkali-resistant bricks have good corrosion resistance to metallurgical slag and cement clinker.
