Abstracts: Concrete is the most widely used construction material for infrastructure but most concrete structures are prone to cracking. Tiny cracks on the surface of the concrete make the whole structure vulnerable because water seeps into degrade the concrete and corrode the steel reinforcement greatly reducing the lifespan of a structure. These micro cracks are therefore precursors to structural failure. Based on the continuous research carried out around the globe, various modifications have been made from time to time to overcome the deficiencies of cement concrete. The report discuss about the performance of the concrete by the microbiologically induced special growth/filler. One such thought has led to the development of a very special concrete known as Bacterial Concrete where bacteria is induced in the concrete to heal up the faults and cracks.
