Abstract
The activity period of concrete is directly proportional to the strength of steel in it, and crack formation in concrete cause corrosion and adversely affect strength of steel. In order to deal with such difficulties, more and more importance is given to developing self-healing concrete that heals itself whenever cracks are formed, with the help of various biological activities. The aim of this research paper is to find out how Bacillus Cereus bacteria influences the various concrete properties. For the current work, bacterial CFU (colony forming unit) of 10, 102, 103, 104, 105 and 106 cells/ml of water were used. In various intervals of curing period, tests were conducted to measure compressive strength, split tensile strength and flexural strength. The results showed that, concrete in which bacteria is present, shows great enhancement in compressive, split tensile and flexural strength in all curing period for all cell concentrations. Bacterial concentration of 105 cells/ml of water showcases the highest strength.KeywordsSelf-healing concrete Bacillus Cereus Compressive strengthSplit tensile strengthFlexural strength
