摘　　要： 采用自制的高效复合激发剂,研究了其对矿渣-钢渣-粉煤灰三掺混凝土工作性能和力学性能的影响。结果表明:复合激发剂的使用,对新拌混凝土的工作性能没有不利影响;复合激发剂对设计等级为C30混凝土抗压强度提高的效果明显,而对C50混凝土的作用效果则有所减弱,其原因在于单位体积混凝土中高水泥含量时,水泥对钢渣的水化在早期具有一定的抑制作用。 A high-performance composite activator was prepared and its influence on the workability and mechanical properties of blast furnace slag,steel slag and fly ash concrete was studied.Results show that the composite activator has no negative effect on the workability of fresh con- crete.The improvement of compressive strength by composite activator was significant for C30 strength grade concrete and was limited for C50 strength grade concrete.The reason was that cement has inhibitory effect on early stage hydration of steel slag with high content cement in unit vol- ume concrete.
