摘　　要：本文研究了铁铬木质素磺酸盐废渣的基本性能 ,利用废渣在不同的蒸压条件下制得了半水石膏 ,并研究了该石膏的水化特性 .研究结果表明 :当压力在 0 .1 MPa,温度在 1 70～ 1The fundametal propety of Iron-complexing lignosulphonate waste slag is studied in this paper. Semi-hydrated gypsum is made under various autoclave conditions and its hydraulic activity is studied by experimentally. The results indicate the optimal synthetical craft is that the pressure is 0.1MPa and proper temperature at 170~180℃. The hydrating activity and hardness propertiess of semi-hydrated gypsum synthesized under above condition.
