Green Ultra-High-Performance Glass Concrete

---

Abstract

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, mechanical properties, and specific rheology. Mixes are designed to suit the rheology and mechanical performances of different concrete applications. Depending on composition and curing conditions, UHPGC can provide improved rheology (mini-slump spread of 260 mm), higher mechanical properties (compressive strength greater than 200 MPa, flexural strength more than 25 MPa). A case study of using this UHPGC is presented through the design and construction of a footbridge.
