Application of ureolysis-based microbial CaCO3 precipitation in self-healing of concrete and inhibition of reinforcement corrosion

Cracking is inevitable in concrete due to its quasi-brittle nature. The presence of micro-cracks will not only impair concrete, but induce reinforcement corrosion by providing paths for the ingress of harmful species. In the past decades, a new technique to repair cracks automatically based on microbial induced carbonate precipitation has become attractive. This paper explored the crack healing potential of reinforced concrete incorporated with...
