Microbial Concrete as a Sustainable Option for Infrastructural Development in Emerging Economies
For sustainable development in emerging economies, it is essential to limit the use of cement in construction, the production of which causes enormous carbon dioxide emissions. This can be achieved by healing the cracks in structures through which harmful substances can penetrate and affect both concrete and reinforcement. One of the most effective autonomous crack healing techniques is possible by using specific bacteria in concrete that have the capability of calcite precipitation in the concrete matrix. In this paper, a state-of-the-art review is presented on microbial concrete as a sustainable construction material. Here, the criteria for bacterial selection, their application methodologies, and the effect of the different bacteria on the mechanical properties of concrete in terms of strength, permeability, and durability are specifically covered. The areas of research on microbial concrete that need to be explored in order to promote its applicability for large-scale infrastructure development have been identified.
