土壤和地下水中的硫酸盐会对地下结构中的混凝土造成破坏。本文通过室内试验，评价了硫酸镁和硫酸钠对普通混凝土和高强混凝土的化学侵蚀损伤。选择的溶液是纯净水和10%硫酸盐溶液(钠和镁)，这是根据韩国的土壤环境确定的。试验方案中的参数包括水胶比、硅灰含量和混凝土抗压强度。讨论了普通混凝土和高强混凝土在特性上的差异，提出了最大限度地提高高强混凝土抗硫酸盐侵蚀能力的方案。(C)1999爱思唯尔科学有限公司。保留所有权利。
Sulfate in soil and groundwater may cause damage to the concrete in underground structures. In this paper, laboratory tests were per formed to assess the damage of chemical attack by magnesium sulfate and sodium sulfate on normal and high strength concretes. The selected solutions were pure water and 10% sulfate solutions (sodium and magnesium), which were determined by consideration of the soil environment in Korea. The parameters in experimental programs were water-binder ratio, silica fume content, and the compressive strength of concrete. Observed differences in the characteristics between normal and high strength concretes are discussed, and a scheme for maximizing the resistance of high strength concrete against various kinds of sulfates is suggested.
