香港作为世界主要商业中心之一,高大建筑鳞次栉比,由于混凝土具有造价低、供应方便和使用制造灵活等优点,是最广泛采用的建筑材料之一,C_(65)以上混凝土已在高层建筑以及工业性侵蚀环境下的结构中使用。例如最近竣工的世界上最高的混凝土建筑—378m 高的中心广场大厦,采用的混凝土为 C_(60)。随着高大建筑的增多和大跨度桥梁、大开间结构需求的不断增加,更需要高强度和高性能的混凝土。
Hong Kong, as one of the world’s major commercial centers, has a large number of high-rise buildings. Because concrete has the advantages of low cost, easy supply, and flexible use, it is one of the most widely used building materials. Concrete above C_(65) has been used in high-rise buildings and industries. Used in structures under aggressive environments. For example, the most recently completed concrete building in the world, the 378m high central square building, uses concrete C_(60). With the increase of tall buildings and the increasing demand for large-span bridges and large bays, the need for high-strength concrete and high-performance concrete is increasing.
