Waste materials as concrete aggregate - A systematic review

Abstract

Abstract Over the last few years, the rate at which metropolitan areas and industries have expanded worldwide has increased, leading to a significant increase in the usage of concrete and the depletion of natural resources like aggregate. This essay aims to thoroughly analyze the use of different wastes as aggregate in cement concrete. Critical reviews have been conducted on the consequences of using such waste materials on the mechanical characteristics of concrete products. From the results of many experiments, it may be inferred that waste can be used in cement concrete instead of natural aggregate. A thorough overview in tabular form is provided for quick access for the benefit of researchers. Further, the outcome of this investigation is expected to accelerate waste utilization for sustainable construction.
