Abstract: A belite-ye'elimite-ternesite cement clinker includes: ye'elimite: 20-50 wt. %; ternesite: 24-50 wt. %; belite: 10-35 wt. %; and free-calcium sulfate (f-C$): 2-10 wt. %. The composition of cement clinker includes an appropriate amount of ye'elimite minerals, ensuring fast early hydration and high early strength of the cement clinker. The cement clinker further includes a certain amount of free-calcium sulfate (f-C$), and is characterized by its good grindability, leading to decreased energy and mechanical losses essential for clinker grinding. This environmentally conscious and energy-efficient method aligns with the global objective of reducing carbon emissions.

Abstract: A low-carbon cement clinker, having the following parameter ranges: alkalinity coefficient C: 1.0?C?1.5; aluminum-sulfur ratio P: P<1.92; aluminum-silicon ratio N: N<1; and limestone saturation coefficient Cs: 0.9?Cs<1.0. The specific range of each parameter value ensures an idea ratio of mineral composition in the low-carbon cement clinker. The ratio promotes a coordinated interaction among different minerals and compounds present when exposed to water, leading to improved strength development and overall performance of the final cement product.
