摘要
基于节能减排和应对气候变化的新要求，研究开发低钙水泥有多方面的重要意义。试验分别采用化学试剂和工业原料，运用化学分析、X-射线衍射、岩相分析等测试手段，初步探讨了高强低钙硅酸盐水泥制备关键技术。结果表明：工业原料中的微量元素能够解决高强低钙硅酸盐水泥的粉化问题；在试验设计的矿物组成和煅烧制度下，w（C2S）设计值在40%-45%，煅烧温度1400-1450℃时熟料性能最优。
Based on the new requirements of energy-saving emission reduction and climate change, research and development of low calcium cement has important meanings in many aspects. Using chemical reagent and industrial raw materials,by chemical analysis, X-ray diffraction and lithofacies analysis, key production technology of high-strength low-calcium Portland cement was discussed. The results show that the trace elements in industrial raw materials can solve the pulverization problem of high-strength low-calcium Port-land cement and in the system of mineral composition and calcination scheme, when w（C2S） design value is 40%~45%and firing temperature at 1400-1450℃, clinker performance will reach the best.
