Abstract

Background/Objectives: Concrete is an inevitable material in construction industry. The major pollution from construction industry was reported from the production of materials like aggregates and cement. The material scarcity, supply-demand gap and environmental pollution insist the construction industry to find an alternative material for concrete matrix. The prime objective of this study is to review the past and recent research on the utilization of alternative materials in concrete production and its applications in construction industry. Materials and Methods: The abundant availability of recyclable waste materials like Construction and Demolition Wastes (C and DW) and industrial byproducts such as fly ash and slag increased the interest of the researchers towards application of these materials as an alternative source for cement and aggregate materials. Findings: Recycled Aggregate Concrete (RAC) showed less strength performance than normal concrete. To attain the similar strength performance of normal concrete, some modifications in the RAC mix design is required. The durability performance was highly improved with the application of industrial by product materials in concrete. Application/Improvement: This study possibly will help to encourage the consumers and further promote the use of alternative materials for concrete production on a larger scale in civil engineering projects.
