The biotechnology approach for sustainable concrete material – a review

Abstract

Biomineralization is a process of formation of calcite from supersaturated solution due to the presence of bacterial cells and biochemical activities. In this article, biological approach towards 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 biomineralization in concrete. The effect of bio-based agent, bacterial solution on various parameters of concrete is discussed. Additionally, the factors for choice of bacteria for biomineralization process are also elaborated. This green biotechnology concept is a promising, environmentally safe and is a best substitute for conventional and current remediation methods to mitigate environmental problems in multidisciplinary fields.
