Application of Bacteria in Repairing the Concrete Cracks - A Review

The cracks and fissures in a concrete structure not only affect its aesthetics, but also indicate significant flaws in the structure or reduce the life of the structure. The fissures can be repaired with adequate remedial measures. Although a great diversity of long term successful repair procedures exists, continued deficiencies are being observed in the final results. Recent studies reveal that the addition of bacteria like Bacillus pasteurii which are capable of producing minerals can promote self healing of the cracks in concrete and that the durability of the concrete can be increased by increasing the concentration of bacteria. The main objective of this article is to review this innovative technique of utilizing bacteria for remediation of cracks in concrete. Different types of bacteria, their growth medium, concentrations, pH conditions and their behavior in compressive strength and durability for remediation of cracks in concrete are discussed in this paper.
