Abstract:

This experiment was conducted to investigate the properties of Bacterial concrete for constructional purposes. In addition to concrete, bacteria named BACILLUS SUBTILIS (along with its nutrients) are added to attain more strength than conventional concrete and to improve properties of concrete. Aim of the study is to test and analyse compressive strength of concrete cubes, optimum dosage of bacteria used and to study properties of cracked specimens by introducing Bacillus Subtilis, which is ureolytic, gram positive (spore forming bacteria), and facultative aerobic. Mechanism: Bacteria converts Calcium (which is present in concrete) as Lime in the presence of oxygen and moisture content. From above mechanism, we analysed that strength of concrete cubes increases, and cracks are healed by itself i.e., it has a self-healing property due to incorporation of bacillus species.
