Also known as alkali-resistant glass fiber, alkali-resistant glass fiber is glass fiber reinforced (cement) concrete (referred to as GRC) rib material, is 100% inorganic fiber, is an ideal substitute for steel and asbestos in non-load bearing cement components. Alkali-resistant glass fiber is characterized by good alkali resistance, can effectively resist the erosion of high alkali substances in cement, strong grip strength, high modulus of elasticity, impact resistance, tensile strength, high flexural strength, non-combustible, antifreeze and temperature resistance. It has strong humidity change ability, excellent crack resistance and impermeability, and is characterized by high designability and easy molding. Alkali-resistant glass fiber is a new type of environmentally-friendly reinforcement widely used in high-performance reinforced (cement) concrete. material.
