摘　　要：粉煤灰和矿粉用于自密实混凝土中均具有一定胶凝性,可部分取代水泥。以乌鲁木齐地区常用粉煤灰和矿粉对天山水泥取代率为变量,配制C30自密实混凝土,对其进行工作性能和抗压强度测试。试验结果表明:粉煤灰和矿粉对天山水泥取代率均为30%时,能配制出工作性能优良、强度合适的自密实混凝土。Fly ash and slag for self - compacting concrete with some cement properties can replace part of cement. Taking different dos- age fly ash and slag in Urumqi to replace the Tianshan cement rate, which compound C30 self - compacting concrete, working perform- ance and cube compressive strength were tested. The results show that when fly ash and slag on Tianshan cement replacement rate is 30% ,it can formulate the self- compacting concrete with good working performance and suitable strength.
