نویسندگان

چکیده

The cement industry could potentially consume large amounts of solid industrial waste in order to improve its sustainability. suitability selected quarry and mine as secondary raw materials (SRM) was examined for the sustainable production following concept a circular economy. chemical, mineralogical, radiological characterization SRM conducted this study. Its potential use low-carbon low-energy belite-sulfoaluminate investigated by incorporating into clinker. Various methods were used characterize cement, including X-ray powder diffraction (XRD), thermal analysis (DTA/TG), isothermal calorimetry. Depending on chemical composition waste, lower or higher allowed be incorporated clinker mixture targeted phase composition. Among samples, differences observed synthesized clinkers, which slightly influenced reactivity but did not significantly change compressive strength final product.
