Bacterial Concrete – A Review
Keywords:
Self-Healing Concrete, Repairing Techniques, CracksAbstract
Concrete is the most widely used building material, in concrete cracks are inevitable due to its inherent vulnerability. Concrete has a poor tensile strength, which causes micro-cracks when the pressure applied exceeds the limit, allowing water and other salts to enter inside. This kind of damage happens early in a building's life and later in its existence. Several repairing techniques are available to repair the cracks. But they are incompatible, expensive, and need constant maintenance. In recent years, concrete bio mineralization has been developed to treat cracks. In this paper, literature study will assess the benefits and disadvantages of various methods. The scientific background that influenced the choice of microbe and metabolic pathway was also considered.
