Abstrait:

The use of recycled waste glass powder (RWGP) as a partial substitute for cement in cement-based materials offers a promising solution for reducing environmental impact and promoting sustainable waste management practices. An experimental study was conducted on a reference material made with Portland-limestone cement CEMII/A-LL42.5R and three other materials containing 50 wt% RWGP with different mean diameters, d50: 16, 18, and 25 µm. The main objective was to analyze the role of RWGP granularity in the short_ and medium-term properties of the cement-based materials. The results showed that coarser RWGP granularity led to an increase in fluidity and Portlandite content, while water demand and mechanical properties decreased. However, the range of RWGP granularities tested did not significantly affect the initial setting time, fresh and dry density, hydration temperature, and water porosity. These findings suggest that the choice of RWGP granularity should depend on the desired properties of the cement-based material.
