Concrete is a construction material that is used world-wide because of its first-rate properties. However, the drawback of this material is that it easily cracks due to its low tensile strength. We all are well aware of the fact that concrete structures are very sensitive to cracking and due to this chemicals and water enters in the concrete and degrade the concrete , and due to this performance of the structures gets reduced and it requires high maintenance cost in the form of repairs. In this report, the following notable points regarding effect of bacteria on compressive strength of concrete, self-healing of cracks in concrete, chemical process for crack remediation, self-healing mechanism of bacteria, application of bacteria in construction field, Advantages and disadvantages of bacterial concrete etc., are observed and identified from the other research works. Cracking in the surface layer of concrete mainly reduces its durability, since cracks are responsible for the transport of liquids and gases that could potentially contain hazardous substances. On the other side the concrete structures have some self healing capacity ,i.e. the ability of a concrete to heal the micro-cracks on it’s own. When micro-cracks growth reaches the reinforcement, not only the concrete itself may be damaged, but also corrosion occurs in the reinforcement due to exposure to water and oxygen, and possibly CO2 and chlorides too. Self-healing of concrete can be done by many ways such as application of specific calcite precipitating bacteria for concrete repair, usage of synthetic polymers such as epoxy treatment, bio-mineralization of bacteria in concrete etc.
