Abstract
The purpose of this study is to investigate the qualities of concrete that contain industrial wastes such as destroyed concrete, SF, and FLY ASH. The use of recycled coarse aggregate (RCA) in concrete, sometimes known as "green concrete," reduces the environmental impact of concrete waste disposal significantly. The study investigates the link between compressive strength and the W-C ratio for RCA concrete made from two different samples of parent concrete. The depletion of natural resources due to the high demand for raw materials in concrete production has raised the need for alternative solutions. Recycled coarse aggregate (RCA) offers a sustainable option by replacing natural coarse aggregate (NCA) in concrete. However, RCA concrete often exhibits inferior properties compared to NCA concrete, which hinders its widespread adoption. This research aims to investigate methods for enhancing the properties of RCA concrete without the use of bacterial additives. The study focuses on evalu
