The U.S. construction industry produces vast amounts of demolition waste, including architectural float glass from building facades. Due to recycling limitations, much of this glass ends up in landfills. This research explores down-cycling architectural glass into concrete as fine aggregate, coarse aggregate, and cement substitutes. Results show improved compressive strength at 10–20% aggregate replacement, while cement substitution beyond 5% reduced strength. Sandblasting minimized visual differences across mixes, highlighting structural and sustainability benefits over aesthetic enhancement. The study supports reusing demolition glass to promote circular economy practices and develop resource-efficient, sustainable building materials for the future built environment.
