摘　　要：应用前期研究获得的熟料最佳组成,利用工业原料合成阿利特-硫铝酸钡钙水泥熟料,研究了原料中不同MgO含量对熟料f-CaO及水泥后期力学性能的影响,研究结果表明:利用工业原料能够合成阿利特-硫铝酸钡钙水泥;随着原料中MgO含量的增加,熟料f-CaO含量增加,水泥后期力学性能降低;中等MgO含量的阿利特-硫铝酸钡钙水泥1d、3d和28d龄期标准砂浆抗压强度分别达到13.5、34.9和61.1MPa.借助于XRD和SEM-EDS等分析测试手段,对该水泥熟料的组成、结构及性能进行了研究.： In this paper, utilizing industrial raw materials was to prepare alite-Ba bearing calcium sulphoaluminate cement clinker researched before. Influence of MgO from raw materials on f-CaO and later mechanical property was also researched. The results show that using industrial raw materials can synthesize alite-Ba bearing calcium sulphoaluminate cement. Increasing amount of MgO lead to f-CaO increasing and later strength decreasing. Cement with the middle amount MgO has 13.5,34.9 and 61.1MPa standard mortar compressive strength at ld,3d and 28d curing age. With the help of SEM-EDS and XRD, the composition, structure and performance of the clinker was analyzed in the end.
