Influence of biogenic treatment in improving the durability properties of waste amended concrete: A review

Bio-precipitation of calcium carbonate through microorganisms has a potential to enhance the durability properties of concrete structures. Microbially induced calcium carbonate precipitation (MICP) has widely been studied and practiced in various applications such as soil consolidation, stone monument restoration and improving the durability properties of concrete. Nowadays use of various industrial by-products or waste materials as a complete or partial replacement of cement and aggregates is practiced to attain sustainable production of concrete. This review article provides the state-of-the-art of recent developments in improving the durability properties of industrial by-product amended concrete combined with the usage of MICP. Recent advances in this review provide insights toward the future developments in introduction of microbial treatment in waste amended concrete. (C) 2020 Elsevier Ltd. All rights reserved.
