This work deals with the valorization of industrial glass waste as supplementary cementitious materials in Ultra High Performance Fiber-Reinforced Concrete (UHPFRC). It aims to take advantage of this type of by-product in order to improve both fresh and hardened performances of conventional cementitious materials. This study concerns the use of glass powder originating from different locations with slight variation in their chemical composition (named transparent, smoked, and opaque) as a supplementary cementitious material (substitution ratio: 20% of the cement weight). Series of standardized tests were performed to characterize the influence of these glass powders on both fresh state properties (slump flow) and hardened state properties of tested UHPFRC. Mechanical properties are measured after cure periods lasting from 2 to 28 days. The study on the microstructure of hardened concrete was made using scanning electron microscopy and water penetration. Obtained results show the beneficial effect brought by the addition of a significant dosage of glass powder (here 20% of the cement weight) on the behavior of concrete in its fresh and hardened state.
Key words: waste valorization / glass powder / ultra high performance fiber reinforced concrete / mechanical behavior / microstructure
