Supersulfated cement (SSC) is a kind of green and low-carbon cementitious material, which has the advantages of low energy consumption, less heat release from hydration and high resistance to chemical attack. This paper mainly introduces the composition, early hydration properties, mechanical properties and chemical attack resistance of SSC. By comparing with Portland cement-based materials, it focuses on the chemical attack deterioration characteristics of SSC, including leaching, general acid attack and sulfate attack. On this basis, the chemical attack deterioration mechanism of SSC is further summarized. It provides theoretical guidance for the engineering application of SSC in different environments.
