Microbial induced calcite precipitation for self-healing of concrete: a review
Microbial induced calcite precipitation (MICP) is a part and consequence of metabolic activities of many bacterial species with involvement of various pathways in presence of specific organic and/or inorganic moieties present in the surrounding environment. Microbial or Bioconcrete is a sustainable and promising technology based on MICP that not only supports the self-healing of concrete structures but also mitigates the detrimental effects of CO2 emissions on environment from the cement industry. The calcite precipitation inside concrete matrix results in crack healing with an improvement in matrix characteristics. This paper reviews the various mechanisms involved in MICP and highlights the role of MICP in self-healing inside cement matrix. The paper further throws light on designing of microbial concrete and explores the beneficiary effects of MICP on various mechanical and durability properties of cementitious materials. Further, the prospective challenges associated with microbial concrete production and the future aspects have been discussed.
