| Abstract Scope |
Belitic cements are binders with a high content of belite (dicalcium silicate, C₂S) compared to ordinary Portland cement, which is richer in alite (tricalcium silicate, C₃S). These cements exhibit specific characteristics that make them attractive from both environmental and technical perspectives, such as lower heat of hydration, higher long-term strength, and reduced CO₂ emissions during production. In this context, the objective of this study was to use waste glass as a partial substitute for conventional clinkers, at levels of 0% and 5%, for the production of belitic cement. The binder was produced in a laboratory muffle furnace, with a maximum calcination temperature of 1200 °C. Cements with 0% and 5% of waste glass were produced in order to evaluate the mineralizing effect of the waste. The cement was characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), and calorimetry. The incorporation of 5% waste glass was found to enhance clinker formation and thermal stability by promoting silicate phase development and C–S–H formation. The results indicated the feasibility of producing belitic cement incorporating waste glass. |
