Brief Introduction: Alkali-resistant (AR) fiberglass, characterised by good alkali-resistance and high corrosion-resistance in cement and other alkali medium, has been used to reinforce cement, gypsum and other inorganic materials. Fiberglass Reinforced Cement (GRC) is a new type of inorganic composite building material. As a light, high strength, incombustible, designable and easy shaped material, it has been widely used in building industry nowadays in the world. Our Products have won the third prize of National Science and Technology Advancement and the second award of Science and Technology Advancement of our country.
High performance AR roving (ZrO2¡Ý16.5%) enabled to resist the very high alkalinity produced by the hydration of Ordinary Portland Cement. The alkali resistance meet the designation requirements of the Japan"NEG" and French "Cem-FIL-¢ò". the durability reach 50 over years and half life period reach 100 over years.
These fibres resisted the very high alkalinity produced by the hydration of Ordinary Portaland Cement and Exhibits a high degree of resistance to acids and alkalis, and have high strand tensile strength. Soaked in 100¡æ saturated Ca(OH)2 solution for 4 hours, remained filament strength>82%. Soaked in 100¡æ, 10% NaOH solution for 1 hour, weigh loss<5%. Alkali-resistant glass fiber Roving used for spray up or mechanical continuous foming GRC.
Premix chopped strand used for site construction and premixed GRC. Water dispersible chopped strand have a sizing system which is water dispersible, allowing full dispersion into individual filaments in mixing in an aqueous environment. They incorporate easily into mixes giving a very large number of distributed reinforcing fibres from a small weight of product. Water dispersible chopped strand used at a low level of addition to prevent cracking & improve the performance of ready mix concrete, floor screeds, rendersorother special mortar mixes.
