摘　　要：混凝土裂缝的危害已成为业内共识,混凝土自修复技术源于生物仿生学,有助于解决混凝土裂缝问题,提升混凝土结构的耐久性和稳定性,降低混凝土结构维护成本,根据不同作用机理可分为主动愈合技术和被动愈合技术两种。本文主要详述基于混凝土自修复材料组分的研究进展,系统归纳了胶凝材料、结晶添加剂、膨胀添加剂、超吸水聚合物等不同组分的自修复作用机理,并对进一步的研究方向提出了建议,为混凝土自修复技术研究提供依据和思路。The harm of concrete cracks has become a consensus in the industry.The self-healing technology of concrete originates from biomimetics,which helps to solve the problem of concrete cracks,improve the durability and stability of concrete structures,and reduce the maintenance cost of concrete structures.According to different mechanisms of action,it can be divided into two types:active healing technology and passive healing technology.This article mainly describes the research progress based on the components of concrete self-healing materials,systematically summarizes the self-healing mechanisms of different components such as cementitious materials,crystallization additives,expansion additives,and superabsorbent polymers,and proposes suggestions for further research directions,providing a basis and ideas for the study of concrete self-healing technology.
