Even though it is possible to reduce the extent of cracking by available modern technology, remediation of cracks in concrete has been the subject of research for many years. Cracks and fissures are a common problem in building structures, pavements, and historic monuments. We have introduced a novel technique in fitting cracks with environmentally friendly biological process that is a continuous self-remediating process. In this study bacillus substile that is abundant in soil has been used to induced CaCo3. It is therefore vital to understand the fundamentals of microbial participation in crack remediation. Cracks in concrete form an open pathway to reinforcement can lead to durability problems like corrosion of the steel rebar’s. furthermore, cracks can cause leakage in case of liquid retaining structures, due to alkali, sulphate, and drying shrinkage to overcome this problem, a variant of smart concrete is rapidly developing, which is known as “self-healing concrete”. The self-healing concrete is one that senses its crack formation and react to cure itself without human intervention. The impact of Eco-friendly micro-organism has been made use of the self-healing process in the current project. The cement industry is a major global contributor to world CO2 emissions (7% in 2019). A major cause of this high percentage is the durability issues associated with concrete, in recent years a new breed on concrete that can heal cracks which are a major cause of these durability. This will introduce this new breed of concrete in its various forms, with particular attention paid to the form which incorporates use of microbes as the healing agents. In recent years a bacteria-based self-healing concrete is being developed to extend the service life. A two-component healing agent is added to the concrete mixture. The agent consists of bacteria and mineral precursor compound. Whenever cracks occurs and water is present the bacteria become active and convert the incorporated organic compounds into the mineral calcium precipitates and can seal and block cracks, allowing autonomous healing.
