Abstract Ternesite (4CaO·2SiO2·CaSO4)-Ye’elimite (3CaO·3Al2O3·CaSO4) (simplified as TY) cement clinker was successfully prepared from steel slag at 1200°C in this study. XRD, TG/DSC and SEM were used to analyze the mineral
composition and hydration products of the TY clinker. The sintering process and hydration mechanism of the TY
clinker were investigated. Results show that a large amount of ternesite and ye’elimite have been formed at
1200°C, while ternesite has not been decomposed. Clinker minerals include ternesite, ye’elimite, gypsum and a
small amount of iron phase. Iron phase from steel slag can promote the formation of liquid phase with the presence of gypsum… More >
