摘　　要：用正交试验法选择熟料率值和硫铝酸钡钙掺量为影响因素,研究了贝利特-硫铝酸钡钙水泥熟料的制备技术和力学性能。研究结果表明,贝利特-硫铝酸钡钙水泥熟料的最佳煅烧温度为1380℃,最佳组成为铝率为1.1,硅率为2.9,石灰饱和系数为0.81,硫铝酸钡钙掺量为9%。在最佳条件下制备的贝利特-硫铝酸钡钙水泥的3d和28d抗压强度分别达到20MPa和80MPa展现了良好的力学性能。利用XRD,SEM-EDS等测试手段分析了该水泥熟料的组成和结构。The preparation and mechanical performance of belite-calcium barium sulphoaluminate cement clinker were investigated by the orthogonal test method taking clinker modulus and content of calcium barium sulphoaluminate（C2.75B1.25A3）as the influencing factors.Results show that the optimal iron modulus,silica modulus,lime saturation factor and content of C2.75B1.25A3 is 1.1,2.9,0.81 and 9% respectively,and the optimal sintering temperature is 1380℃.The compressive strength of the cement prepared under these conditions reaches to 20MPa and 80MPa at 3d and 28d curing ages. The mineral constituents and structures of the clinker were analyzed by the means of XRD, SEM-EDS.
