Belitic cementsCement are bindersBinders with a high content of belite (dicalcium silicate, C₂S) compared to ordinary Portland cementCement, which is richer in alite (tricalcium silicate, C₃S). These cementsCement 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 glassWaste glass as a partial substitute for conventional clinkers, at levels of 0% and 5%, for the production of belitic cementCement. The binderBinders was produced in a laboratory muffle furnace, with a maximum calcination temperature of 1200 °C.

Belitic cementsCement are bindersBinders with a high content of belite (dicalcium silicate, C₂S) compared to ordinary Portland cementCement, which is richer in alite (tricalcium silicate, C₃S). These cementsCement 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 glassWaste glass as a partial substitute for conventional clinkers, at levels of 0% and 5%, for the production of belitic cementCement. The binderBinders was produced in a laboratory muffle furnace, with a maximum calcination temperature of 1200 °C. CementsCement with 0% and 5% of waste glassWaste glass were produced in order to evaluate the mineralizing effect of the waste.
