The usage of cement has been increased throughout the world which has severe effect on the environment. replacement of cement in concrete is in very much need, for which several materials came into existence like flyash, silicafume GGBS and geopolymers etc.one such material which will act as cementinious materials is used in the study which will reduce cracks and fissures in concrete by utilizing microbiologically induced calcite (CaCo3) precipitation called Bio Mineralization produced by Bacillus subtilis in the presence of chemicals. In this project, bacterial concrete is prepared under grade of concrete M25 and Natural fiber is added in total volume of concrete in desired level which will cure the cracks automatically by forming calcium carbonate precipitate as well as to achieve more Compressive strength and Flexural strength. To avoid corrosion, the bacterial concrete along with natural fibers is used which results in self healing process.

In this study, the behavior of bacterial fibre concrete was investigated experimentally. Various parameters like compressive strength, flexural strength and splitting tensile strength of specimens for bacterial fibres concrete have been studied. Then these values for bacterial and bacterial fibre concrete are compared with the conventional concrete.
