Abstract – Globally, the Cement industry accounts for approximately 5 percent of current anthropogenic carbon dioxide (CO2) emissions. The usage of cement has been increased more over the world results in the air pollution which leads to the ozone depletion. The obtained reviews of experiments to determine the optimum amount of fly ash that could be added to replace cement in concrete, as between 25-35% additional fly ash results in a significant increase in compressive strength. Concrete are the most important materials used in construction industries where the external forces more than the design loads mainly the lateral forces which leads to the deformation and produce cracks in the joints of the structural member. To overcome these type of problem like crack formation and usage of cement content used for repair works can be reduced by using the self-healing bacterial concrete, these are materials Which heals the crack automatically when the cracks are formed. These self-healing are achieved by means of using the Biological healing aspect by using the bacterial concrete. Bacteria are used during the mixing of concrete will heal the cracks the automatically by means of it screeds known as calcium carbonate precipitate.

Key Words – High Volume Fly Ash Concrete, Bacterial Concrete
