Sustainable building and the green building movement have made great strides in the previous decade, prompting a re-evaluation of construction methods and materials worldwide. Concrete remains the preferred material due to its high strength, long service life, and fire resistance. Enhancing sustainability in concrete production is crucial given its extensive use. Nanotechnology offers environmental benefits by reducing waste, toxicity, carbon emissions, and energy consumption. In this work, concrete sustainability is enhanced by incorporating waste-based nanomaterials including nano zirconium oxide (ZrO2), nano silicon carbide (SiC), nano zinc oxide (ZnO), nano cobalt oxide (Co3O4), nano clay, and carbon nanotubes. This step contributes toward developing Green Concrete. © 2025 Elsevier B.V., All rights reserved.
