Cracks in concrete are inevitable and are one of the inherent weaknesses of concrete. Water and other salt seep through these crack corrosion initiates, and thus reduces the life of concrete. So there was a need to develop an inherent biomaterial, a self-repairing material which a remediate the cracks and fissures in concrete. Bacterial concrete is a material, which can successfully remediate cracks in concrete. This technique is desirable because the material precipitation induced as a result of microbial activities is pollution free and natural. As the cell wall of bacteria is anionic metal accumulation (calcite) on the surface of the wall is substantial, thus the entire cell becomes crystalline and they eventually plug the pores discusses the plugging of artificially made cuts in cement mortar which was cured in urea and CaCl2 medium.
