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.
