Concrete is very vulnerable to cracking which allows chemicals, salts and water which initiates the corrosion and reduces the life of concrete structures. So it is better to adopt a self-repairing technique which can reduce the fissures and cracks. Bio-concrete is one of the remedial techniques. In this project Bio-concrete is prepared under the grade of concrete M20 by using various amounts of bacteria (Bacillus subtilis) to enhance the strength and durability properties of concrete. The
