Self-healing concrete received an attention in previous few decades. This paper reviews the analysis conducted on self-healing in previous two decades. Self-healing approaches, differing types of healing agents used, incorporating procedures, and analysis techniques square measure highlighted during this paper. The development of cracking and crack- healing, materials used for crack-healing and also the strategies and techniques utilized throughout the method, the outcomes of experiments mentioned by numerous researchers from their work square measure highlighted. From the literature review, it had been terminated that the crack breadth sizes up to 0.1mm can be healed with self-produced self- healing mechanism, whereas, crack scrutinize to 1 mm are often well with autonomous self- healing mechanism. it had been determined that the healing potency was entirely smitten by the concrete exposure to corresponding surroundings, the kind of healing agent used, procedures and techniques followed.
