Everyone wants to break the monotony of life in some way. Yes, Concrete’s crack formation due to brittling should be changed, thus our project “self healing of bacterial concrete using BACILLUS SUBTILIS”, just as our skin heals the wound. This Project deals with the novel technique of self healing of cracks in concrete by the microbial induced calcite precipitation in concrete by the bacteria BACILLUS SUBTILIS. In our Project , the non pathogenic spore forming soil bacterium “BACILLUS SUBTILIS” is added in the making of concrete along with water in the concentration of 105 per ml. During the crack formation, this bacteria gets activated due to its exposure to air and water. The bacteria taking its food calcium lactate and reacting with cement particles emits CaCO3 by the process of BIOCALCIFICATION. Our Project deals with the experimental finding of its compressive, tensile, corrosion and healing properties.
