80年代以来,一些发达国家相继研制出高性能混凝土(简称 HPC),使混凝土进入高科技时代。我国十年前步入其研究行列,也取得了不少研究和应用成果。HPC 的优点有三,其一,由于其高强和超高强特性,可使混凝土结构尺寸大大减小,减轻结构自重和对地基的荷载,并大幅度降低工程造价;其二,由于其具有高工作性,可以减轻施工劳动强度,节约施工能耗;基三,由于其高耐久性,可延长建筑物的使用寿命。
Since the 1980s, some developed countries have successively developed high-performance concrete (HPC for short), bringing concrete into the high-tech era. Ten years ago our country entered the ranks of its research, but also made a lot of research and application results. HPC has three advantages. First, due to its high strength and ultra-high strength, it can greatly reduce the size of concrete structure, reduce the weight of the structure and the load on the foundation, and greatly reduce the project cost. Second, due to its high workability , Which can reduce the labor intensity of construction and save construction energy consumption. Basis III, because of its high durability, can extend the service life of buildings.
