Review on microbial induced calcite precipitation mechanisms leading to bacterial selection for microbial concrete

There are various mechanisms through which bacteria precipitate calcium carbonate, out of which a few have been recognised for application in concrete for crack healing. This paper first presents a review of work carried out on microbial concrete from the viewpoint of microbial induced carbonate precipitation (MICP) mechanisms. The mechanisms so far applied to concrete have limitations, especially with regard to their applicability to structures...
