工业生产大量排放SO2,使混凝土发生硫化发应,对混凝土结构的耐久性造成了严重影响.国内外混凝土中性化研究多集中于一般大气环境下的混凝土碳化问题,混凝土硫化研究较少.总结了近年来有关混凝土硫化问题的研究现状,从硫化机理出发,分析了硫化后混凝土的性能劣化规律,探讨了混凝土硫化速率的影响因素,并讨论了当前有关混凝土硫化研究的一些重要问题.%A large amount of SO2 gas from industrial production reacts with concrete,which has a serious influence on durability of concrete structure.The domestic and foreign researches of concrete neutralization mainly focus on the concrete carbonation in general atmospheric environment;nevertheless,scant studies concern concrete sulfuration.This paper summarizes the research of concrete sulfuration in recent years,and reveals the mechanism of concrete sulfuration.The concrete deteriorated properties suffered sulfuration are analysed,and the influence factors of concrete sulfuration are considered.Finally,some important issues of are dis cussed.
