摘要：Cracking in the surface layer of concrete mainly reduces its durability, since cracks are responsible forthe transport of liquids and gasses that could potentially contain deleterious substances. So the objective of the presentinvestigation is to study the potential application of bacteria, Bacillus sphaericus to increase different mechanicalstrength of the concrete. Conventional and bacterial concrete was prepared and its strength was evaluated usingstandard Indian Specifications. A significant increase of compressive strength, split-tensile strength and flexuralstrength was observed for respective B1 (100ml) and B2 (150ml) cell concentrations after 28 days of bio-curing. TheUltra-sonic pulse velocity value of B2 concrete revealed the self-healing properties when compared with theconventional concrete. The present study concludes that inexpensive alternative for laboratory growth media wouldpotentially bring down the cost of the bacteria based self-healing sustainable concrete.
