摘　　要：智能型混凝土修补材料,是指能够自动识别混凝土微裂纹等结构缺陷并自动激发本身的修补物质对混凝土的裂纹等缺陷产生修补作用,从而恢复或提高混凝土的强度与使用寿命的一类修补材料。这种智能化的修补方式使得该类修补材料具有良好的开发、应用前景。本文介绍了近年来该类别修补材料的研究状况。并详细介绍了水泥基渗透结晶型智能修补材料和自修补智能混凝土体系的修补机理,使用与研究发展状况。Intelligent concrete patching material can discern little concrete crackles or other structure defects and auto - excited mending material, to repair them. Thus the strength and service life of the concrete can be recovered or improved. The development and application prospect of intellectual patching material is very good for the intelligent mending way. In this paper, the research state of this kind of patching material in recent years is introduced. Especially the mending mechanism, the study and application state of cementitious capillary crystalline patching material and intellectual self-healing concrete system are discussed in detail.
