Abstract
Objective To reduce energy consumption in the cement industry， this paper reviews and analyzes research findings on supersulfated cement （SSC）， which could contribute to the green and low-carbon development of the cement industry.
Progress The primary research focus on SSC includes its hydration， performance， and durability. SSC is a new type of low-carbon cement composed of granulated blast furnace slag （GBFS）， gypsum， and an alkaline activator. The use of highly reactive GBFS in SSC effectively promotes hydration， while waste gypsum supports later-stage hydration and strength development. Different types of activators have varying effects on hydration promotion， and high-belite sulfoaluminate cement clinker has shown excellent performance in enhancing early strength development. Adding appropriate amounts of calcium formate and nano-SiO2 to SSC can further accelerate hydration reactions and improve early strength. SSC generally has a long setting time， good volume stability， and strong resistance to sulfate and acid attack. However， its poor carbonation resistance and freeze-thaw performance are significant obstacles to wider application.
Conclusions and Prospects Addressing the issues of low early mechanical strength， poor carbonation resistance， and inadequate freeze-thaw performance is crucial for the broader application of SSC. Overcoming these challenges has strong practical implications for the promotion and use of SSC.
