Abstract

Highlights: Utilization of industrial byproducts in construction industry reduces environmental burden. Replacement of cement and aggregates with these byproducts substantiate the resources. Application of MICP technology to enhance the durability of concrete structures is well documented. MICP improves the durability properties of waste amended concrete structures. Abstract: 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.
