GRC is the English abbreviation of GlassfiberReinforcedConcrete, and the Chinese name is glass fiber reinforced concrete. GRC is a kind of fiber concrete composite with alkali-resistant glass fiber as reinforcement and cement mortar as matrix material. GRC is a kind of material that expresses designers' imagination through mold modeling, texture, texture and color. At present, GRC molds include cement mold, FRP mold, wood mold, silica gel mold and steel mold, among which GRC steel mold has the best surface smoothness and angular dimension accuracy. A standard is an open and transparent thing. With standards, producers and consumers are familiar with the raw materials, quality and performance of a commodity, which actually makes the "contractual" relationship of commodity trading more certain and the rights and obligations of both parties more clear. Standardized enterprises all have the same characteristics, and always hope that the market will be open, transparent, standardized and healthy; And speculators always want to muddy the water and profit from it.

Promoting industrial upgrading through standard optimization has been proved to be the only way for industrial development in developed countries. With the rapid development of economic globalization and informatization, the status and role of standards are becoming more and more important. Newton famously said, "If I see farther than others, it is because I stand on the shoulders of giants." GRC Eurostandard is a giant like GRC industry, and we should quickly climb to a new height with the help of GRC Eurostandard system. Because the surface of glass fiber is very smooth, the transition zone of glass fiber-cement interface is the weakest link in ordinary GRC, and AR fiber can only exert its strength efficiency of 14.3% theoretically. According to the interface theory, if the interfacial adhesion between glass fiber and cement is too weak, a large number of fibers will be pulled out under load, and the GRC strength is very low; However, if the binding force is too strong, the stress on the fiber surface will be concentrated, which will lead to fiber damage, brittle fracture of the material, and the strength and plasticity will be reduced.
