The basic composition of GRC materials are cement, sand, fiber and water, in addition to polymer, additives used to improve the later performance of the materials. Cement: Usually the cements used in GRC are mainly rapid hardening sulphoaluminate cement and low alkalinity sulphoaluminate cement, Portland cement and white Portland cement. Fiber: The fiber in the GRC material must be alkali resistant glass fiber, which include alkali resistant glass fiber roving, chopped glass fiber yarn, alkali resistant glass fiber mesh cloth. European and American countries require the zirconia content in the glass fiber should not less than 16.5%. The polymer: the polymer usually added is acrylic emulsion, also named acrylate copolymer emulsion. Additive: Usually we selectively added superplasticizer, superplasticizer, retarder, early strength agent, antifreeze, anti rust agent and other additives containing products. When there is the steel reinforcement or steel embedded parts, do not use calcium chloride based additives. Other materials: We can selectively use fire.
