红层地区地下水对水工建筑物的硫酸盐侵蚀性,作为特定的工程地质问题见于黄河上游水电工程。地下水广泛存在的这种侵蚀现象,长期以来便开展对其性质规律,并探求对其防治的途径。本文试图通过工程实例及给定条件下的现场混凝土耐蚀试验,探讨不同水泥在相同介质中的抗蚀能力并从中找出规律,在此提出以供商榷。 The sulfate erosion of hydraulic structures by groundwater in the red beds is seen in the upper reaches of the Yellow River as a specific engineering geological problem. This erosion phenomenon, which is widespread in groundwater, has for a long time carried out its laws of nature and explored ways to prevent it. In this paper, we try to discuss the corrosion resistance of different cements in the same medium and find out the law from the corrosion resistance of concrete under the given conditions and given conditions, which are proposed here for discussion.
