Abstract

Biomineralisation is a process of formation of calcite from supersaturated solution due to the presence of bacterial cells and biochemical activities. In this article, a biological approach towards the development of sustainable construction materials is studied. Evidence of bacterial precipitation of calcite has led several research groups to explore the possibility of adopting this process in the area of construction materials. The goal of this review paper is to highlight the application of biomineralisation in concrete. The effect of a bio-based agent and bacterial solution on various properties of concrete is discussed. Additionally, the factors in the choice of bacteria for the biomineralisation process are also elaborated. This green biotechnology concept is a promising, environmentally safe substitute for conventional and current remediation methods to mitigate environmental problems in multidisciplinary fields.
