Here an attempt was made by using the bacteria “Bacillus megaterium”. Concrete cylinders and prisms were cast with and without addition of bacteria were cast and its split tensile strength and flexural strength were examined. There was an increase in split tensile strength and flexural strength with addition of bacteria. From Scanning Electron Micrography analysis, it is noted that pores were partially filled up by material growth with the addition of the bacteria.
