摘　　要：本文研究了钢渣、矿渣、石膏和粉煤灰对钢渣水泥抹面砂浆性能的影响。结果表明:钢渣水泥复合材料抗压强度和抗折强度随着钢渣掺量的增加而呈减小的趋势;矿渣(20%)复配改性钢渣水泥复合材料,28d最佳抗压强度和抗折强度(49.2MPa和6.8MPa)分别较未掺矿渣的提高了3.3%和16.2%;当脱硫石膏掺量在3%时,可提高钢渣-水泥-矿渣力学性能;当增塑剂掺量控制在0.4%,水泥抹灰砂浆施工性能较好,砂率在1:4时,钢渣水泥抹灰砂浆28d抗压强度可达到13.5MPa(满足M10等级要求),当砂率为1:5时,钢渣水泥抹灰砂浆28d抗压强度可达到7.5MPa(满足M5等级要求)。This paper studied the effects of steel slag, slag, desulfurization gypsum and fly ash on properties of mortar. The results showed that the compressive strength and flexural strength of steel slag-cement composite material declined with the increasing of steel slag. The 28d compressive strength and flexural strength of steel slag-cement composite material with 20 wt.% slag is 49.2MPa and 6.8MPa respectively, which increased by 3.3% and 16.2% compared with that without slag. Mechanical properties of steel slag-cement-slag composite material could be improved when the content of desulfurization gypsum was 3wt.%. When the content of plasticizer was 0.4wt.%, the workability of cement mortar was good, In addition, the 28d compressive strength of steel cement mortar reached to 13.5MPa （meeting the requirements of M 10） when the sand ratio was 1：4. Besides, the 28d compressive strength of steel cement mortar reached to 7.5MPa（meeting the requirements of M5） when the sand ratio was 1：5.
