Green Ultra-High-Performance Glass Concrete

First International Interactive Symposium on UHPC, 2016
This paper presents research work on the development of a green type of ultra-high-performance concrete at the University of Sherbrooke using ground glass powders with different degrees of fineness (UHPGC). In UHPGC, glass is used to replace quartz sand, cement, quartz powder, and silica-fume particles. UHPGC design is based on particle packing density,
