Abstract

The use of recycled concrete aggregate (RCA) in concrete, as both partial and full replacements for natural coarse aggregate, is gaining traction in the construction industry. This practice not only reduces the demand for virgin aggregate but also offers a solution to the environmental issues posed by concrete waste and the extraction of natural resources. This study aims to develop an economically viable solution using recycled aggregate in structural concrete to mitigate environmental impact. The objective is to investigate the properties of recycled aggregate and assess the performance of concrete when standard coarse aggregates are replaced with RCA in varying percentages. Concrete performance is evaluated based on compressive and flexural strength with RCA replacement levels at 15%, 30%, 45%, and 60%. The mix designed for this study is of Grade M25. Non-destructive testing, specifically the Rebound Hammer Test, is also conducted on the concrete. Experimental results indicate that the optimum RCA replacement level is up to 45% for compressive strength and up to 30% for flexural strength.
