According to the abstract released by the Intellectual Property India: "In this study, bacillus subtilis bacteria and calcium lactate were used in experimental investigations to stop the concrete cracks. The ability of bacteria to survive in an alkaline environment determines their selection. River sand mixes and crushed stone sand mixes were used in place of fine aggregate in M20 and M40 grade concrete, containing varying percentages of Bacillus subtilis bacteria and calcite lactate (5%, 10%, and 15% of cement weight). For all mixes, experimental studies were conducted to examine the impact of bacteria on the compressive and flexural strengths of concrete at seven, fourteen, twenty-eight, sixty, ninety, 180, 270, and 365 days of curing. 10% bacterial solution substitution in cement produced the highest strength in both the compressive and flexural strength tests."
