Concrete suitable for high-altitude, large-temperature-difference, dry and intense-radiation environment and preparation method thereof
The invention discloses concrete suitable for high-altitude, large-temperature-difference, dry and intense-radiation environments and a preparation method of the concrete. The concrete is prepared by mixing the following raw materials in parts by mass: 10-15 parts of cement, 1-5 parts of a mineral admixture, 45-55 parts of gravel, 16-25 parts of sand, 5-10 parts of porous fine particles, 0.01-0.5 part of an additive, 0.01-0.5 part of a functional component and 8-10 parts of water. The concrete prepared by the invention can have the advantages of early strength, no cracking, self-curing, high durability and the like after being cast, molded and hardened, can be applied to bridges, pavements, water channels, pile foundations and civil buildings in high-altitude, large-temperature-difference, dry and intense-radiation environments, and has a significant effect on improving the durability of concrete structures in western regions of China, improving the construction efficiency and improving the construction quality. The method is of great significance to guarantee the safety of national major strategic engineering.
本发明公开了一种适用于高海拔、大温差、干燥和强辐射环境的混凝土及其制备方法。所述混凝土由以下原料按质量比混合而成：水泥10～15份、矿物掺合料1～5份、碎石45～55份、砂16～25份、多孔细颗粒5～10份、外加剂0.01～0.5份、功能性组分0.01～0.5份、水8～10份。本发明制备出的混凝土可以在浇筑成型硬化后具有早强、不开裂、自养护、高耐久等优点，可应用于高海拔、大温差、干燥和强辐射环境下的桥梁、路面、水渠、桩基、民用建筑，对提高我国西部地区混凝土结构的耐久性，保障国家重大战略工程安全具有十分重要的意义。
