摘　　要：以硫酸钠、二水石膏、氯化钙、氢氧化钙为激发剂,对高掺量焚烧炉渣-水泥复合胶凝材料早期力学性能进行研究。试验结果表明:四种激发剂中,硫酸钠能更好地激发炉渣胶凝材料的活性,当硫酸钠掺量为2%时,试样的3d、7d、28d抗压强度分别达到12.5MPa、18.6MPa、27.6MPa。随着激发剂掺量的增加,高掺量炉渣复合胶凝材料的早期力学性能变好。Effect of four kinds of activator（sodium sulfate, dihydrate gypsum, calcium chloride calcium hydroxide）on the early mechanical properties of large volume of waste incineration bottom ash compound cementitious material is studied. The results show that compared with the other three activators, sodium sulfate can stimulate the activity of compound cementitious material more effectively. When the content of sodium sulfate is 2%, 3d compressive strength is 12.5MPa, 7d compressive strength is16.8MPa and 28 d compressive strength achieves 27.6MPa. The early mechanical properties of large volume of compound cementitious material get better with increasing compound activator.
