摘　　要：旨在探讨在面对水泥生产中的能源消耗和碳排放挑战时所应采取的应对之策,重点关注低碳胶凝材料的研究进展。综合分析了硫铝酸盐水泥和高贝利特水泥的性能及应用,并特别关注了两者结合制备的高贝利特硫铝酸盐水泥。然而,尽管新型水泥在减少碳排放方面取得了进展,低温煅烧水泥的性能提升和能耗降低仍需平衡。针对镁质胶凝材料,讨论了以轻烧氧化镁为基础的氯氧镁水泥和硫氧镁水泥。这些材料具有较低的煅烧温度和碳排放,但在耐水性和力学性能方面存在挑战。通过改性研究,特别是促进水化产物的生成,可以显著提高这些材料的性能。The purpose of this paper is to discuss the countermeasures to meet the challenges of energy consumption and carbon emission in cement production,focusing on the research progress of low-carbon cementing materials.The properties and applications of sulfoaluminate cement and high Belite cement are analyzed comprehensively,and special attention is paid to the high Belite sulfoaluminate cement prepared by combining them.However,while the new cement has made progress in reducing carbon emissions,the improved performance and lower energy consumption of low-temperature calcined cement still need to be balanced.Magnesium oxychloride cement and magnesium oxysulfide cement based on light fired magnesia are discussed.These materials have lower calcination temperatures and carbon emissions,but present challenges in terms of water resistance and mechanical properties.The properties of these materials can be significantly improved through modification studies,especially by promoting the generation of hydration products.
