This study aims to address sustainability challenges in construction by exploring the structural performance and environmental benefits of incorporating pozzolanic waste glass (WG) into ultra-high-performance reinforced concrete (UHPRC) beams.

A comprehensive evaluation of UHPRC beams was conducted, incorporating varying ratios (10%, 20% and 30%) of WG powder alongside a consistent 0.75% inclusion of basalt fiber. The investigation encompassed the entire UHPRC production process, including curing, casting and molding, while evaluating workability and physical properties. Furthermore, the environmental impact, particularly CO₂ emissions associated with UHPRC mixture components, was also assessed. Type K thermocouples were employed to analyze temperature dynamics during fabrication, providing valuable insights.

The findings demonstrate positive implications for using pozzolanic WG as a cement substitute in UHPRC beams.

This research stands out for its unique focus on the combined effects of incorporating recycled pozzolanic glass waste on the structural performance and environmental footprint of UHPRC beams.
