摘　　要：智能混凝土是通过将极少量具有某种特殊功能的材料复合于传统的混凝土材料中形成的具有多功能特性或某一种特殊功能特性的新型土木工程结构材料。与其他智能材料相比,智能混凝土是多功能本征性智能材料,可从本质上提高工程结构的性能。自感知混凝土(纳米混凝土、碳纤维混凝土)、自阻尼混凝土和自愈合混凝土等是智能混凝土研究的热点。总结了近年来作者在智能混凝土的制备、性能、机理,以及智能混凝土结构等方面的研究成果,并指出需进一步研究的问题。Smart concrete is a sort of advanced structural materials which is fabricated through adding some special additives into traditional concrete, and has multifuctions as compared with traditional concrete, as well as good mechanical propoerties. Therefore, smart concrete is an intrinsic smart material and is a good candidate to improve structural performance. It includes concrete with nanophase materials and carbon fibre reinforced concrete with self-sensing properties, self-damping concrete and self-repairing concrete. The fabricdation method, functional property, mechanism and smart concrete-based structures reesearched by authors are summarized. The further trends and challenge topics in this area are also figured out.
