Abstract:
Micro cracks formed in concrete allow moisture ingress to the central core and cause slow damage. It has been studied that a certain ureolytic bacteria called Bacillus Sphaericus, reacts with moisture to form CaCo3 which is used as a protective sealant against degrading factors. The objective of the present investigation is to study the influence of bacterial species i.e. B.sphaericus on the mechanical properties of baggage replaced concrete. Here we have made an attempt to incorporate dormant bacteria in the concrete matrix which will contribute to the strength of the concrete. Water which enters the concrete will activate the dormant bacteria which in turn will give strength to the concrete through the process of metabolically mediated calcium carbonate precipitation. In this work we have studied the effect of this bacterium in concrete by varying measures of bacteria in bagasse ash replaced concrete. Concentration of 105 cells/ml of bacteria was used in making the concrete mixes. Tests were performed for compressive strength, Split tensile strength at the age of 28 days.
