绿色高性能混凝土与科技创新

Green High Performance Concrete and Innovation

水泥与水泥基材料科研近期宜在宏观、粗观、亚微观三个层次上进行．波特兰水泥与常规混凝土存在着可持续发展的问题．生产１ｔ熟料水泥同时排放１ｔ左右的ＣＯ２．中国水泥与混凝土需量猛增，形势更为严峻．因此提出发展绿色高性能混凝土，并扩大其应用范围．从宏观、粗观、亚微观三个层次说明开发ＧＨＰＣ（ｇｒｅｅｎｈｉｇｈｐｅｒｆｏｒｍａｎｃｅｃｏｎｃｒｅｔｅ）对中国和世界的重要意义．

It is pointed out in this paper that nowadays the cement and cement based materials should be studied on the grand, macro, and submicro three levels. Portland cement and normal concrete are facing the serious sustainable development problem. About 1 ton CO_2 pollution is caused by 1 ton cement clinker production. The seriousness of the development of green high performance concrete in China is described by the author from the point of view of grand, macro,and submicro three levels as the requirement of cement concrete in China is increasing rapidly.
