초록

Self-healing concrete received an attention in last few decades. This paper reviews the research conducted on self-healing inlast few decades. Self-healing approaches, different types of healing agents used, incorporating procedures, and evaluationtechniques are highlighted in this paper. The phenomenon of cracking and crack-healing, materials used for crack-healing andthe methods and techniques employed during the process, the outcomes of experiments discussed by various researchers fromtheir work are highlighted. From the literature review, it was concluded that the crack width sizes up to 0.1mm can be healedwith autogenous self-healing mechanism, whereas, crack size up to 1mm can be healed with autonomous self-healingmechanism. It was observed that the healing efficiency was wholly dependent on the concrete exposure to correspondingenvironment, the type of healing agent used, procedures and techniques followed.
