Abstract

Rapid urbanisation has accelerated consumption of concrete making it the most consumed artificial material. Present day concrete is one of the largest sources of anthropogenic greenhouse gas emission and is not sustainable. Microbial precipitation of CaCO₃ is a promising way of emulating nature's sustainable ways. This paper reviews current progress and potential of this technology. Prior research on the modes of application of the technology and consequent gains in strength and durability of construction materials has been summarised. Imperatives for a quantitative estimate of sustainability are identified. Progress necessary for industrial adoption of the technology has been discussed.
