Description
This experimental study deals with the crack healing ability of the bacteria. The crack in the concrete is the major problem in construction field. Crack in concrete structure tend to expand further and eventually require costly repairs. To solve this problem, we have introduced a novel technique by fitting crack with environmentally friendly biological procedure that is a continuous self-remediating process. In this study Bacillus Sphaericus that is abundant in soil have been used and it is added in different proportions in M25 concrete in the form of liquid. The cubes and cylinders specimen should undergo compressive and split tensile test at 7, 14, 28 days. This study showed increase in strength by addition of bacterial solution, precipitation of Calcium Carbonates in micro cracks and test results are been compared.
