Alkali-resistant Glassfibre is major material that can be used in Glassfibre Reinforced Concrete (GRC) , it is 100 % inorganic material , it is also ideal replacement of steel and asbestos in unloaded cement component part . GRC has good Alkali-resistance,can valid resist the corrosion of high - alkali substance of cement ,grasp wrap strength,high elastic modulus,resist and freeze melt,resist and roll over intensity high,incombustible,high frost-Resistance, moist-resistant,resist cracks , excellent impermeability . It has designable and easy shaped material . As a high performance Glassfibre Reinforced Concrete products that can be widely used in building, it is a new type green Environmental Protection reinforced material. ZrO2 content 14.5%-16.7%.
