摘要

混凝土对裂缝的形成非常敏感。由于大裂缝会危及耐用性，因此可能需要修复。然而，这些维修工程提高
了混凝土的生命周期成本，因为它们是劳动密集型的，而且结构在维修过程中会被废弃。1994年，C.Dry是第一个提
出有意在混凝土中引入自愈特性的人。在接下来的几年里，一些研究人员开始研究这个话题。本次审查的目的是对
当今可用的不同自我修复方法进行深入比较。在这些方法中，一些旨在改善自生裂缝愈合的自然机制，而另一些则
旨在通过嵌入合适的愈合剂的胶囊来改性混凝土，使裂缝出现后以完全自主的方式愈合。在这篇综述中，特别注意
了所使用的愈合剂和胶囊的类型。此外，根据所使用的触发机制对各种方法进行了评估，并关注了由于自愈而恢复
的属性。
