This study explores a more sustainable approach to construction by using dunite powder rock as a partial substitute for cement to reduce the global carbon emissions, Due to the reduction of cement percentage. The replacing cement at levels of 25%, 45%, and 75%, we tested how this mineral affects both the flow of wet concrete and the dry concrete and also the ultimate strength of the finished structure. Our findings reveal that dunite isn't just a filler; it actually creates a denser internal structure that can maintain or even enhance compressive and tensile strength up to significant replacement level of 50–75%. While exceeding this limit eventually leads to a drop in strength because there is too little cement left to bind the mix, the overall results prove that dunite is a highly effective, eco-friendly alternative that can help the building industry shrink its carbon footprint without sacrificing structural integrity.
