酸雨对混凝土建筑物和文物损坏机理的研究

介绍了酸雨对混凝土建筑物和文物损坏机理的宏观分析，水泥中加入少量石膏，可延缓凝结时间，但当加入量大，将引起水泥膨胀，以致溃裂，探讨了酸雨对混凝土建筑物与文物损坏的微观分析，特别是酸雨等生成各种硫酸盐，通过从化学反应原理上分析了酸雨中二氧化硫与混凝土中钙离子反应生成石膏机理，从石膏特性上探讨了酸雨对混凝土建筑物和文物侵蚀机制，并由此提出了酸雨条件下保护混凝土建筑物和文物应对措施。

Acid Rain on the Damage Mechanism of Concrete Buildings and Cultural Relics

Introduces the acid rain macro analysis of the mechanism of concrete damage of buildings and cultural relics , adding a small amount of gypsum, cement can delay setting time, but when adding quantity is big, will cause cement expansion, so that debacle, and acid rain on concrete structure and microscopic analysis of damage of cultural relics, such as acid rain are particularly to generate a variety of sulfate, through the analysis of the acid rain from the chemical reaction principle of sulfur diox-ide generated by reaction with calcium ions in the concrete mechanism of gypsum, acid rain are discussed from the gypsum charac-teristics of concrete buildings and cultural relics of the erosion mechanism, and thus puts forward the protection of concrete build-ings and cultural relics under the condition of acid rain .
