摘　　要：通过研究不同水灰比的普通混凝土、不同掺量的粉煤灰混凝土和不同粗骨料类型混凝土在二氧化硫腐蚀下的质量变化率、强度、硫化深度,揭示了混凝土在二氧化硫环境中的腐蚀规律。结果表明:粉煤灰混凝土在抵抗二氧化硫腐蚀方面优于普通混凝土,轻骨料混凝土仅仅在减轻硫化深度方面优于普通混凝土。Through research the quality rate, strength and sulfide depth under the corrosion of sulfur dioxide with different water cement ratio of ordinary concrete ,different replacement of fly ash concrete and different kinds of coarse aggregate concrete, the corrosion law about the concrete in sulfur dioxide environment have been revealed. The results showed that fly ash concrete is better than ordinary concrete in terms of corrosion resistance to sulfur dioxide and lightweight aggregate concrete is better than ordinary concrete only in the aspect of reducing sulfide depth.
