Internal stresses (due to mechanical loads, temperature changes, etc.) can induce microscopic cracks in portland cement concrete, which may continue to grow upon the application of additional stresses. These cracks can provide pathways for harmful chemicals to ingress. Research in the field of concrete materials has shown that it is possible to develop a smart cement-based material that is capable of self-healing by leveraging the metabolic activity of microorganisms to induce biogenic calcium carbonate precipitation. This project investigates the application of a using this biomimetic approach to improve the corrosion resistance of concrete.
