Concrete plays a vital role as a construction material in the world. This project presents the results of an experimental investigation carried out to evaluate the influence of Bacillus Subtilis and Bacillus Licheniformis on the compressive strength, split tensile strength, flexural strength, water absorption and its self-healing properties. An attempt is made to heal these cracks by the addition of the bacteria in the concrete and also to increase of the strength of the concrete. Each bacteria of concentration 105 cells/ml are added. Tests were performed at the ages of 7, 14 and 28 days. The applicability of specifically calcite mineral precipitating bacteria to fill the cracks in concrete and the bacteria chosen must have the self-healing capacity and the bacteria used must be nonpathogenic and sustainable. It is found that the cracks in the concrete have been healed and the formation of calcite precipitation is observed using Scanning Electron Microscopy (SEM). Usage of bacteria like Bacillus Subtilis, Bacillus Licheniformis improves the strength and durability of concrete through selfhealing effect.
