Abstract
A green ultra-high-performance glass concrete (UHPGC) with a compressive strength (fc) of up to 220MPa was prepared and its fresh, mechanical, and microstructural properties were investigated. The test results indicate that the fresh UHPGC properties were improved when the cement and quartz powder were replaced with nonabsorptive glass-powder (GP) particles. The strength improvement can be attributed to the GP’s pozzolanicity and to its mechanical performance (very high strength and elastic modulus of glass). The microscope investigation revealed the formation of a hydration rim around cement and GP particles. UHPGC provides technological, economical, and environmental advantages compared to traditional ultra-high-performance concrete (UHPC).
