Concrete structures are vulnerable to cracks due to seepage of water and structural instabilities etc. These cracks can be closed by external sealants. But now incorporating bacteria in concrete helps in healing the cracks effectively. The Paper featuring the innovative technique in sealing the cracks autonomously along with that strength and durability parameters were analyzed. The Production of calcium carbonate was observed under optical microscope in order to show the bonding capability with concrete matrix. Compare to conventional concrete, self-healing concrete enhances the strength up to the addition of 0.5% bacteria and nutrient to the cement weight. But quick healing capabilities were observed when addition of bacteria and nutrient increases. Resilient features of bacteria were observed when it subjected up to the heat of 75oc.
