Cracking is a frequent cause of complaints in the concrete industry. Cracking can be the result of one or a combination of factors such as drying shrinkage, thermal contraction, restraint (external or internal) to shortening, sub grade settlement, and applied loads or can also be caused by freezing and thawing of saturated concrete, alkali- aggregate reactivity, sulphate attack, or corrosion of reinforcing steel. So, there is a need for the development of such an inherent biomaterial, which is a self-repairing material and can remediate the cracks and fissures in concrete. Bacterial concrete is one among such a material, which can successfully remediate cracks in concrete. This technique is an ecofriendly desirable as well as a natural method that can be taken into consideration in recent concrete industry era. The Paper discusses the comparative study of concrete self healing capability using different types of bacteria viz Bacillus Sphacricus, B. Cohnii. Hence this is a Biological Remediation of cracks repairment.
