Synthesis and properties of belite-ye’elimite-ternesite cement clinker at 1200 °C
Belite-ye’elimite-ternesite (BYT) cement is a new type of cement with low energy consumption and carbon dioxide emissions. Notably, the sintering temperature of ye’elimite (C4A3$) is approximately 150 °C higher than that of ternesite (C5S2$) and belite (C2S). To facilitate the simultaneous presence of three minerals, the mineralizer (CuO) was used to reduce the formation temperature of C4A3$ in this work. Thermogravimetric (TG) was utilized to investigate the sintering temperature of minerals within the clinker. Furthermore, X-ray powder diffraction and scanning electron microscope were applied to analyze the phase composition and microstructure, respectively. The findings reveal that BYT cement clinker can be synthesized in one step at 1200 °C by adding 4% CuO. Ternesite (C5S2$) initiates hydration by 28 d, contributing to the stable development of medium-term strength. Optimal mechanical properties were observed with a ratio of C4A3$:C2S:C5S2$ at 40:50:10, achieving a 28 d strength of 43.7 MPa.
