Study on Strength and Durability Properties of Bacteria Concrete

Abstract: Cracks in concrete are unavoidable and it is one of the inherent weaknesses of concrete. Sometimes water and other salts seep through these cracks because of which corrosion initiates, and thus reduce the life of concrete. So there was a need to develop a self-repairing material which can remediate the cracks and fissures in concrete and bacterial concrete is one of them. In this research, M40 grade of concrete is prepared by adding various amount of bacteria (Bacillus subtilis) to improve strength and durability properties.The bacterial concrete specimens and conventional concrete specimens were immersed in 5% H2So4for 28 days and it was found that bacterial concrete shows better performance comparatively.
