介绍了3类高贝利特水泥的特点和活性贝利特的研究现状,重点介绍了粉煤灰贝利特水泥的原材料、制备方法、水热合成产物、熟料组成、水泥水化和物理力学性能及耐久性等方面的研究进展,分析了料块水热合成–煅烧法和料浆水热合成–煅烧法的差异、粉煤灰贝利特水泥研究开发中存在的问题与原因及发展前景,对粉煤灰贝利特水泥的进一步研究从有效的水热处理方法、合理的熟料煅烧温度制度、石膏种类与掺量、粉磨细度的优化、以及适宜缓凝剂和减水剂的开发和应用等几个方面提出了相关建议。
The characteristics of the three types of high belite cement were introduced. Recent development on active belite was reviewed. The detailed information on studies of fly ash belite cement, including raw materials, preparation processes, hydrothermal-synthesized products, mineral composition, hydration, physical and mechanical properties and durability were represented. The difference between block hydrothermal-calcination process and slurry hydrothermal-calcination process was comparatively discussed. The problems in the development of fly ash belite cement and the possible reasons, the prospect of developing and application of the cement were analyzed. Several aspects were proposed for further studies of fly ash belite cement.
