为达到脱硫石膏砌块减重且保证强度的目的，利用工业废料脱硫石膏、粉煤灰，掺加少量水泥、膨胀聚苯颗粒作为混合材料，研究脱硫石膏实心砌块的力学性能及表观密度的变化。结果表明，制备脱硫石膏砌块最优配比为：木钙减水剂0.42%、柠檬酸缓凝剂0.12%、木质纤维素0.06%、水泥15%、粉煤灰10%、脱硫石膏75%、聚苯颗粒25%，此条件下可获得密度为964 kg/m3，28 d抗压强度达10.1 MPa的轻质脱硫石膏砌块。

Industrial waste gypsum, lfy ash mixed with small amount of cement and expanded polystyrene particles are used as mixed material to reduce weight and ensure the strength through experimental study on the mechanical properties and the change of apparent density of desulfurization gypsum block. The experimental results show that the optimal ratio were 0.42% lignosulphonate calcium water reducers, 0.12% citric acid retarder, 0.06% lignocellulose, 15% cement, 10% lfy ash, 75% desulphurization gypsum, 25% polystyrene particles. Light desulfurization gypsum block with density of 964kg/m3 and 10.1MPa of 28 d compressive strength can be obtained.
