摘要: 超硫酸盐水泥是一种绿色、低碳胶凝材料,具有低能耗、低水化热以及高抗化学侵蚀性能等优点。本文主要介绍了超硫酸盐水泥的组分、早期水化特性、力学性能和耐化学侵蚀特性等。通过与硅酸盐水泥基材料对比,重点评述了超硫酸盐水泥基材料的耐化学侵蚀劣化特性,包括溶出性侵蚀、一般酸性侵蚀和硫酸盐侵蚀,在此基础上进一步总结了超硫酸盐水泥基材料的侵蚀劣化机理,为超硫酸盐水泥基材料在不同环境中的工程应用提供理论指导。

Abstract: 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.

Key words: supersulfated cement, hydration property, chemical attack, deterioration mechanism
