摘　　要：通过盐雾箱加速劣化,对高性能混凝土和普通混凝土之间抵抗氯离子侵蚀能力的差异进行研究,并探究了包括迎风面、背风面和侧风面的不同混凝土面抗氯离子侵蚀规律的差异。研究结果表明同一表面高性能混凝土抵抗氯离子侵蚀能力优于普通混凝土,而对于同一试块,迎风面的氯离子侵蚀程度高于侧风面和背风面。The chloride ingression properties of different surfaces in both high performance concrete and normal concrete were investigat- ed.In the research, specimens made from both kinds of concrete were put into the salt spray cabinet to accelerate chloride ingressiorLExplored the difference of the law of the chloride ingress into the windward surface,crosswind surface and leeward surface for the concrete.The result showed that the chloride ingress into the windward surface was much more serious than that of the crosswind surface and leeward surface for the same concrete,while for the same surface,the chloride resistance of high performance concrete was better than that of normal concrete.
