Milled Waste Glass Powder in Magnesium-Silicate-Hydrate Cement: Technical and Environmental Assessment
https://orcid.org/0000-0001-7977-0718
This study investigated replacing microsilica with waste glass for preparing MgO-SiO2 formulations to form magnesium-silicate-hydrate (M-S-H). The mechanical performance and microstructural development of the samples were supported by an assessment of their environmental impact. The obtained results indicated that microsilica can be partially replaced by waste glass (i.e., 50% by weight replacement) in MgO-SiO2 formulations without sacrificing the compressive strength of samples, whereas the complete replacement with waste glass did not reveal favorable outcomes in terms of performance. The reactivity and solubility of the silica source played a key role in the formation of M-S-H, which contributed to the strength development in samples containing microsilica. Alternatively, samples containing waste glass as their only silica source revealed limited M-S-H formation and brucite, accounting for their poor mechanical performance. The predetermined treatment of waste glass should be carefully chosen, which could also affect the outcomes of the life cycle assessment (LCA).
