摘　　要：实验研究了不同高贝利特水泥(HBC)和硅酸盐水泥(PC)配合比,不同缓凝剂掺量以及不同粉磨细度对HBC-PC复合体系水泥的物理性能的影响。结果表明,HBC与PC混合时,HBC的适宜比例为50%～80%,以50%为最佳。在最佳HBC掺量下,采用二水石膏作缓凝剂,水泥中w(SO3)控制在2.0%～3.0%时水泥具有较好的早期和后期强度;采用硬石膏作缓凝剂,水泥w(SO3)控制在2.0%～3.5%时综合效果较好。当HBC掺量为50%,w(SO3)为2.6%±0.2%时,其复合体系水泥的适宜粉磨细度为320～400m2蛐kg。Effect of different High Belite Cement(HBC)and Potland Cement(PC)ratio,retardant agent and fineness on physical perfor-mance of HBC-PC composite cement were studied.The results show that when blending HBC and PC,the appropriate ratio of HBC is50%～80%and the most suitable one is50%,If HBC ratio is50%,using dihydrate gypsum as retardant agent,when w(SO3)ranged from2.0%to3.0%,the composite cement has excellent early and late strength,if using anhydrous gypsum as retardant agent,the gen-eral effect is the better when w(SO3)of composite cement is controlled in2.0%～3.0%.Finally,if HBC ratio is50%and w(SO3)is2.6%±0.2%,the appropriate grinding fineness degree of composite cement is320～400m2/kg.
