A Study on the Strength of the Bacterial Concrete

2018-1-3  Bacillus megaterium can be produced from lab which is proved to be a safe and cost effective. The compressive strength of concrete cube is maximum with the addition of bacillus megaterium bacteria for a cell concentration of 105 cells per ml of mixing water. The addition of bacillus megaterium bacteria increases the compressive strength of concrete. In standard grade concrete the compressive strength is increased up to 10.92% at 28 days by addition of bacillus magaterium bacteria when compared to conventional concrete. The addition of bascillus megaterium bacteria showed significant improvement in the split tensile strength and flextural strength than the conventional concrete. From the above it can concluded that bacillus megaterium
