摘　　要： 依据GB/T18046—2008中的检测方法,用6种对比水泥对2种矿渣基复合掺合料进行了活性指数检验,研究了对比水泥对矿渣基复合掺合料胶凝活性评定的影响规律。结果表明:复合掺合料活性指数的检验结果因所采用的对比水泥的不同而产生显著的差异,其活性指数与对比水泥胶砂抗压强度之间存在显著的负相关关系。矿渣基复合掺合料专用的化学激发剂对水泥品种来源具有良好的适应性。 Activity indices of GGBS based composite admixture were tested with six different kinds of reference cement according to GB/T 18046-2008. The effect of reference cement on the activity evaluation of GGBS based composite admixture was investigated. The results showed that there were significant differences among activity indices that tested by different reference cement. A significant negative correlation was found between activity index of GGBS based composite admixture and mortar compressive strength of reference cement. The chemical activator used for GGBS based composite admixture has good adaptability to different kinds of reference cement.
