Mechanical and Microstructure Study of the Self Healing Bacterial Concrete

Abstract:

Concrete largely used for construction material, degrades with the development of cracks that becomes easy passage for entry of chemicals and harmful compounds. Self healing capability is helpful to mitigate the deterioration of the concrete structures. This research work focuses on the self healing behaviour and mechanical properties of the bioconcrete supplemented with three different bacteria namely Bacillus sphaericus, Bacillus cohnii and Bacillus megaterium. Concrete supplemented with Bacillus cohnii exhibited 35.31% increase in compressive strength compared to control mix after 28 days. Concrete supplemented with other bacteria Bacillus sphaericus and Bacillus megaterium also showed enhanced compressive strength. Interestingly, addition of bacteria aided in healing of artificially generated cracks by formation of CaCO₃minerals. Maximum amount of healing (bacterial precipitation) which could be quantified as calcite minerals present in the bacterial concrete was 11.44% with B. cohnii confirmed by the Scanning Electron Microscope (SEM) with Energy Dispersive Spectroscopy (EDS).
