Combined Effect of Li, Cu and S Doping on Structure and Hydration of β Dicalcium Silicate

This study investigates the effect of Li, Cu and S on the structure and hydration of the beta modification of dicalcium silicate (β-C₂S). The doped β-C2S phase was prepared by burning beta-C2S with dopant sources. The structure of prepared β-C2S samples was examined using X-ray diffraction, scanning electron microscopy and infrared spectroscopy. Heat evolution during hydration was assessed by isothermal calorimetry. A positive effect on cement hydration was observed for several dopant combinations.
