摘　　要：随着世界各国工业化进程不断加快,酸性物质大量排放到大气中,酸雨区逐渐扩大,酸雨酸性也逐渐增强。此外,酸雨对混凝土结构产生较大的危害,处于酸雨区的混凝土结构耐久性大幅下降。该文分别综述了不同酸性侵蚀介质、不同pH值溶液、不同混凝土水胶比和不同矿物掺合料、酸雨与多因素耦合对混凝土的影响以及混凝土预防酸雨的措施,并对进一步的研究提出建议。With the continuous acceleration of industrialization in the world, a large number of acid substances are discharged into the atmosphere. The acid rain area is gradually expanded, and the acid rain is gradually more acidic. In addition, acid rain does great harm to concrete structure, and the durability of concrete structure in acid rain area decreases greatly. In this paper, the influence of different acid erosion media, different pH values, different concrete water-binder ratio and different mineral admixtures, acid rain and multi-factor coupling on concrete and measures to prevent concrete from being eroded by acid rain are reviewed, and suggestions for further research are proposed.
