Influence of Firing Regime and Potassium Ions on Synthetic Preparation of Belite Clinker

The study of the influence of selected temperature regime and potassium ions on the process of synthesis of belite (2CaO·SiO2, C2S) was carried out. The basic raw material was calcium carbonate (CaCO3) and amorphous silica (SiO2). The dosage of both components was based on the stoichiometric ratio o...

Summary:The study of the influence of selected temperature regime and potassium ions on the process of synthesis of belite (2CaO·SiO2, C2S) was carried out. The basic raw material was calcium carbonate (CaCO3) and amorphous silica (SiO2). The dosage of both components was based on the stoichiometric ratio of CaO:SiO2 in belite. The modification of the raw meal was carried out in the form of potash, K2O. Potash was dosed in the form of potassium carbonate, K2CO3, and potassium sulfate, K2SO4. The firing process was performed in a superkanthal furnace with two temperature modes, firing temperature: 1150 °C / 3 hours soaking and 1450 °C / 5 hours soaking. The evaluation performed by the experiment was based on mineralogical analysis by XRD analysis.
