介绍了高性能砼的特点及海港工程所用砼的性能要求,提出以砼氯离子扩散系数为耐久性指标设计海港工程用高性能砼;以福州连江黄岐半岛海港桥梁——布袋澳大桥预制箱梁为工程背景,在综合考虑砼的强度、工作性、均匀性、耐久性、密实性和体积稳定性的情况下,讨论了海港工程高性能砼原材料的选择,提出了海港工程高性能砼配合比设计方法。
The characteristics of high performance concrete and the performance requirements of the concrete used in the harbor engineering are introduced. The concrete chloride ion diffusion coefficient is taken as the durability index to design the high performance concrete for harbor engineering. The bridge of Huangqi Peninsula Harbor in Lianjiang of Fuzhou - the prefabricated box beam For engineering background, considering the strength, workability, uniformity, durability, compactness and volume stability of concrete, the selection of high performance concrete raw materials for harbor engineering was discussed and the performance proportion of high performance concrete for harbor engineering Design method
