Preparation, manufacture and properties of new ß-belite cement
Original language description
The objective of this work is the optimization of the synthesis of ß-belite cement. Belite cement (dicalcium silicate) is a promising material due to a lower CO2 emission and lower energy consumption during its production. Cement with a high content of ß-belite was prepared from ground limestone, amorphous silica and alkaline silicate solution. The raw materials were mixed, the mixtures were compacted and then burnt in an electric furnace. Different CaO/SiO2 ratios, firing temperatures, raw materials and firing time were tested. The samples were characterized by XRD, SEM and free lime content. Differences between the cements with high content of ß-belite prepared on a laboratory scale (tens of grams) and on a larger scale (tens of kilograms) were studied. Belite cement prepared on a larger scale had better properties compared to a laboratory scale. Optimal synthesis of ß-belite cement consisted of mixing ground limestone, silica fume and liquid potassium silicate and burning at temperature 1100°C for more than 2 hours.
