As the aging leads to dilapidation of reinforced concrete structures due to formation of cracks through which chlorides and other chemical agents promote corrosion. There is need of repair or maintenance of such existing structures. Therefore, self-healing, a leading-edge method for durability enhancement, has gained a lot of importance. In this paper, the various self-healing techniques for concrete, including intrinsic healing, capsule-based healing, vascular healing and also immobilization along with healing mechanism of some materials are reviewed with their comparisons. Moreover, a comprehensive study is also done on the different tests for assessment of self-healing in concrete at macro-scale, micro-scale and nano-scale to determine and characterize healing product and to evaluate their mechanical properties.
