土壤对混凝上的腐蚀的类型和程度取决于混凝土质量和水泥品种以及土壤中所含腐蚀介质的种类和数量。高密实性和高强度混凝土的耐腐蚀性较好。硫酸盐对混凝土的侵蚀作用主要与土壤中硫酸盐的含量以及其饱水程度有关。硅酸盐混凝土在土壤中的中性化值较大。

The corrosiveness of concrete by soil generally depends on the quality of concrete, the types of cement used, the categories and quantities of corrosive mediums contained in soil. A high density and high strength concrete possesses a fairly good corrosion resistance. The erosion of sulfate to concrete is mainly related to the content of sulfate in soil and the saturation level. The neutralizatoin value of Portland—cement concrete placed in soil is very high.
