Literature Review on Self-Healing Concrete by Using Bacteria

The purpose of this literature paper is to determine the use of bacteria is one of the most rising as well as bright approaches. The primary component of a concrete construction is cement. In concrete structure crack development is a typical phenomenon, it reduces durability & strength. Also analyse the impact of oxygen and water on the crack portion. In this study use of bacteria because the bacteria are having repair ability. This paper focuses on the mechanical properties of Bacillus family self-healing concrete. The mix proportion of material are taken while performing on bacterial based concrete. In the process of research and development of self-healing concrete, it is observed that there are main component of healing agent is bacteria which can produce or make the Calcite as a by-product of their activity. When these bacteria are incorporated into concrete, they can fill the cracks and voids with calcite, reducing permeability. Also improve concrete’s mechanical properties and Enhance durability and resistances to degradation. In this study there are some kind of test and bacteria were used for performance in concrete mixture and to highlight the crack process also to point on the crack width how bacterial as well as bacteria concrete can heal the crack in minimum time period of crack developed on it. Current study used the bacteria in capsules formed to prevent the bacteria in other chemical reaction used capsule they can work on projection membrane of bacteria.
