Self-healing concrete (SHC) is a novel concept that aims at enhancing the durability of concrete structures and its sustainability through cracking self-repair. This review comprehensively explores the major underlying mechanisms involved in the self-healing process such as autogenous healing and chemical healing that include microbial-induced calcium carbonate precipitation (MICP) method and capsule-based chemical healing. The study also explores recent developments in the areas of microbial self-healing, chemical admixtures, and nanomaterials that have amplified the performances of the self-healing process. Further it also assesses the possibility of implementing advanced approaches such as the use of machine learning (ML) to predict and enforce self-healing action in response to several environments. A critical analysis of case studies of SHC in actual civil engineering structures of infrastructure development reveals the ability to enhance the durability of concrete with less maintenance costs. This paper offers a rich understanding of the present scenario, issues, and prospects for self-healing concrete as a resilient, sustainable, and economically viable material for constructing the future world. As to future developments, it is necessary to further work on creating several function healing systems, eco-friendly materials, and ways of increasing rates of SHC to apply it in the construction industry.
