Ability of living organisms to form minerals has lead to development of bacterial concrete. It is a biomaterial and a self repairing material it remedies cracks and fissures in concrete. Concrete with Bacillus pasteruil bacteria with filler sand has been successful this has aided restoration of historical monuments by microbial precipitation.
Bacterial have been effectively used for improving the strengths of concrete beams and other structures, which have air gaps and micro cracks. The bacterial Bacillus pasteruil in the concentration of 8.6*108 cells/ml can improve the strength of the concrete by forming a calcite layer in the crack. Thus, the strength of the beams have improved back to 81.97% of the original strength.
