Enhance the Bacterial Activity on Compressive Strength of Cement Concrete and Quantification of Crack Healing in Bacteria Based Self Healing Concrete

The investigation work is for improvement of the compressive strength of concrete by self healing property. We used Bacillus sphaericus as bacteria and calcium lactate as nutrient. We used M25 M30and M35 grade of concrete for the work. It was observed that for M25 grade of bio concrete the compressive strength was nearly 17 more than that of conventional concrete after 3 days, nearly 20.5 after 7 days, nearly 22.53 after 14 days, nearly 25.27 after 28 days of curing. It was observed that for M30 grade of bio concrete the compressive strength was nearly 15.5 more than that of conventional concrete after 3 days, nearly 24.75 after 7 days, nearly 27.44 after 14 days and 29.47 after 28 days of curing.
