Abstract:Concrete is one of the widely used material in the field of civil engineering constructions. The concrete structures undergo several issues which affect the durability of concrete. In all those several effects cracking is one which affects the mechanical strength of concrete. The main aim of the present study is to repair the cracks in the concrete using the biological repair technique. This technique involves the use of ureolytic bacteria for the purpose of healing of cracks which is known as Biocementation (or) microbiologically induced calcite precipitate (MICP). The Bacillus subtilis is the bacteria used in the study as solution replacing 30% of the water during the concrete mix. A comparison of strength is made between conventional concrete and bacterial concrete in which results came out to be in favor of bacterial concrete. The study result showed that there was a noticeable increase in the strength of bacterial concrete.

Keywords: Bacillus subtilis, bacterial concrete, bio-calcification, compressive strength and Split tensile strength
