A new type of green ultra-high-performance glass concrete (UHPGC) was developed at the Université de Sherbrooke using waste glass having varying particle-size distributions (PSD). UHPGC provides several technological, economical, and environmental advantages. It reduces the production cost of ultra-high performance concrete (UHPC) and carbon footprint of traditional UHPC structures. This paper presents the rheological and mechanical properties of selected UHPGCs. The rheology of the UHPGCs was improved by using non-absorptive glass particles. UHPGC greatly improves the concrete microstructure, resulting in higher mechanical and durability properties, which are comparable to those of the conventional UHPC. These strength and rigidity gains were due to the fact that the glass particles acted as inclusions with very high strength and elastic modulus. A special mix design of UHPGC was developed for innovative pedestrian bridges at the Sherbrooke University campus. Concrete performances of this UHPGC are also presented in this paper.
