Abstract

In the production of concrete, the exploitation of (SCMs) supplementary cementitious materials like fly ash and copper slag has gained a substantial amount of attention due to the fact that these materials have the ability to improve the characteristics of concrete while simultaneously addressing certain environmental concerns. The main purpose of this research is to evaluate the influence that integrating fly ash and copper slag does on the performance of concrete in a variety of different areas. A series of experimental investigations were Conducted in order to analyze the qualities of both fresh and hardened concrete. While copper slag can be used in varying percentages (10%, 20%, 30%, 40%, and 50%), M- Sand is used to completely replace natural fine aggregate. Fly ash is used as a substitute material for cement at a constant rate of 30%. In order to determine the extent to which it is possible to incorporate fly ash and copper slag into concrete mixes without disrupting the workability of the concrete, the qualities of fresh concrete, such as its workability and its setting time, were evaluated. In order to gain a better understanding of the effects that these SCMs have on the strength of concrete, the properties of hardened concrete, including compressive strength, tensile strength, and flexural strength, were investigated in detail. The results of this Research paper offer significant contributions to the environment and the possible advantages and obstacles related to the integration of 30% fly ash and 30% copper slag in concrete.
