Abstract
The ultra-high-performance glass concrete (UHPGC) is an advanced UHPC innovative pioneer in sustainable concrete technology. UHPGC technology can provide environmental benefits through the use of post-consumer glass. Economic benefits through the decrease in the amount of landfilled materials are undesirable as they are neither biodegradable nor environmentally friendly and could reduce the costs for UHPC. Compressive strength greater than 150 MPa and mini-slump spread diameter bigger than 250 mm can be achieved, depending on the UHPGC composition and curing temperature. The glass powder (GP) milled to the micro-scale is subjected to low pozzolanic reaction and works as a catalyst speeding clinker dissolution forming calcium silicate hydrate (C-S-H). These reactions have a good positive influence on both UHPC's mechanical and microstructural properties. This paper overviews previous studies carried out as partial or full replacement of sand or quartz sand (QS), quartz powder (QP), and silica fume (SF) by the use of milled waste glass (WG) in UHPC mixture. Nowadays, the sustainability of the construction sector must be a priority for the scientific community. So, the development of the used materials and methods to extend the lifetime of concrete structures is mandatory.
