摘　　要：选择熟料率值和硫铝酸钡钙掺量为影响因素,通过正交试验研究了贝利特—硫铝酸钡钙水泥的合成条件和力学性能,并利用XRD、SEM-EDS等测试手段分析了该水泥熟料的组成和结构。结果表明:煅烧温度为1 320℃时,制备贝利特—硫铝酸钡钙水泥熟料最优化组合为铝率1.4,硅率2.3,石灰饱和系数0.77,硫铝酸钡钙矿物的质量分数为9%。在此条件下该水泥的3 d和28 d抗压强度分别达到11.4 MPa和64.8 MPa,展现了良好的力学性能。Synthesis conditions and mechanical performance of belite- calcium barium sulphoaluminate cement clinker were investigated by the orthogonal test taking clinker modulus and content of calcium barium sulphoaluminate （C2.75B1.25A3S^-） as the influencing factors. Resultsshow that the optimal iron modulus, silica modulus, lime saturation factor and content of C2.75B1.25A3S^- are 1,4,2.3,0. 77 and 9%, respectively. The optimal sintering temperature is 1320℃.The compressive strenglh of the cement prepared under these conditions reaches up to 11.4 MPa and 64.8 MPa at 3 d and 28 d curing ages, respectively. The mineral consfitueras and structures of the clinker were analyzed by means of XRD, SEM - EDS.
