Abstract
Concrete is an enormously used building-material in the construction industry all over the world. It tends to crack because it has low tensile strength. Cracking in concrete will uncover the steel bars and it lowers the quality of concrete and embedded steel bars. This paper presents the results of tests performed to examine the influence of different concentrations of Bacillus megaterium-10086 (MTCC) bacteria on the strength and permeability of M30 and M70 grade concrete. The concentrations of three distinctive cells of microorganisms were used to make eight series of concrete mixes. Compressive strength, tensile strength, and water permeability tests were conducted in accordance with Indian Standard codes. Experimental results revealed that the incorporation of B. megaterium in concrete improved the strength and reduced the permeability of concrete.
