The primary thought of this review is to assess the strength and durability properties of high strength concrete specimens by replacing cement with bacteria for healing cracks. Concrete is the most commonly used construction material all around the world. Cracks are formed due to various reasons. The cracks act as a pathway through which water and toxic salts enter. This causes corrosion and also leads to failure of structure. Repair and Rehabilitation works are costly to be done. In order to overcome this, bacteria is induced into the concrete which leads to the process of Microbial Induced Calcium Precipitate (MICP). The cracks heal by self-healing mechanism and results in crack free concrete structure. It also improves the compressive and tensile strength. In this article a new bacterium has been cultured and identified and is used as a self-healing material in M30 Grade concrete.
