Self-compacting concrete (SCC) and high-performance concrete (HPC) are examples of special concretes that
have been developed as a result of the ongoing evolution of societal needs and the desire for alternatives to
traditional concrete. This study investigates the potential of copper slag, a by-product of copper smelting, as a
sustainable component for SCC, HPC, and beyond, with a special focus on 3D printable mixtures and highperformance self-compacting concrete (HPSCC). The study highlights current gaps in the literature. Little
attention has been paid to potential copper slag’s function as a chemical/mineralogical active component in
comparison to a wider application as a filler substitute in traditional cement-based composites. A thorough
analysis outlines advantages and disadvantages of using copper slag, including improved strength and durability,
lower water and natural material consumption, and environmental benefits. However, there are challenges
indeed, including like its glassy particle surface, prolonged setting times, and enhanced risk of bleeding and
segregation. Overall, copper slag still is a promising ingredient for high-performance and ecologically friendly
concrete solutions because its benefits exceed its disadvantages. Future research should focus on optimizing the
replacement of aggregates and binder components in HPSCC and 3D printable concrete to fully harness the
material’s potential.
