在我国社会主义现代化建设中,需要各种特殊性能的水泥。开采石油,要用高温高压下流动性能好的水泥;建造大坝,要用水化热低的水泥;建设海港,要用耐腐蚀、抗冻和干湿交替性能良好的水泥;生产钢筋混凝土构件,要用快硬、高强水泥;制造水泥管,要用能产生化学自应力的水泥;建筑装饰工程,需要白色和彩色水泥;一些特殊混凝土工程,则要求使用膨胀水泥、耐高温水泥,以及在负温下能快速硬化的水泥等等。当今世界新的技术革命,对水泥品种提出了新的要求。海洋工程要用耐海水侵蚀和耐冲刷的水泥;原子能工程要用防辐射的高强水泥;航天工程要用耐高温冲刷的水泥;高速公路要用耐磨
In our country’s socialist modernization construction, cement with various special properties is required. The exploitation of petroleum requires the use of high-temperature and high-pressure cements with good flow properties; the construction of dams requires the use of low-temperature cement, and the construction of seaports requires the use of cements that are corrosion-resistant, frost-resistant, and dry-wet alternately; and the production of reinforced concrete components. To use fast, high-strength cement; to manufacture cement pipes, to use cement that can produce chemical self-stress; for building decoration, white and colored cement are needed; for some special concrete projects, it is required to use expansive cement, high-temperature-resistant cement, and to be negative. Cement that can quickly harden at warm temperatures, etc. The new technological revolution in the world today sets new requirements for cement varieties. Marine engineering uses seawater resistant and erosion-resistant cement; Atomic energy engineering uses radiation-resistant high-strength cement; Aerospace engineering uses high-temperature-resistant scouring cement; Highway uses wear-resistant
