【摘要】 水泥土搅拌法的施工工艺及水泥土的应用特点使其经常处于具有侵蚀性离子的环境中.为此,利用试验模拟了侵蚀性离子的存在,对不同离子浓度、不同水泥掺量的水泥土试件在各龄期进行了试验研究,并对侵蚀机理进行了分析.结果表明,SO42-和Cl-对水泥土的侵蚀性均比较明显,其中Cl-的侵蚀性与水泥的掺量有关;而SO42-的浓度在一定范围内对水泥土的强度具有一定的增强作用.对水泥土在复杂工程环境中的应用具有参考价值.更多还原

【Abstract】 Based on the laboratory tests on cemented soil under ionic erosion,the factors that influences mechanical properties of cemented soil were analyzed.The results show that erosion caused by ions has evident effects on cemented soil.The higher erosion-resistance of cemented soil corresponds to an optimal proportion of cements.Particular amounts of Na₂SO₄ can improve the strength of cemented soil.The conclusion obtained through the tests can be referred in both design and application of soil-cement in ionic environments.更多还原
