: Crack formation is very common phenomenon in concrete structure which allows the water and different type of chemical into the concrete through the cracks and decreases durability and strength. Self-healing mechanism in the concrete which helps to repair the cracks by producing calcium carbonate crystals which block the micro cracks and pores in the concrete. Bacillus pasteurii, Bacillus subtilis and B. sphaericus , Bacillus megaterium which are mainly used for the experiments by different researchers for their study. The selection of the bacteria was according to their survival in the alkaline environment The condition of growth is different for different types of bacteria. For the growth, bacteria were put in a medium containing different chemical at a particular temperature and for a particular time period. In this study Self-Healing agents such as Bacillus Sphaericus used Bacteria is mixed in concrete with calcium lactate. Bacteria used in proportion of 10, 20, 30 ml/liter and calcium lactate 10g/liter water. A Comparison study is made with this concrete subjected to compressive strength of normal concrete and Bacterial concrete.
