The absence of portlandite and lower alkalinity in the supersulfated cement (SSC) system make it sensitive to being carbonated, especially, since the early-age carbonation would suppress the further hydration of SSC and its performance development. Here, the low-calcium silicate minerals (CxS, hydra...
