摘　　要：利用脱硫石膏作为基本材料,通过加入活性掺合料、碱性激发剂、促凝剂、减水剂、保水剂、耐水胶粉等进行复合改性,配制成一种自流平材料。抗折和抗压强度分别达到6.8 MPa和29.2 MPa,软化系数达到0.82,各项性能指标均优于JC/T985-2005和JC/T1023-2007的标准要求。用脱硫石膏配制自流平材料可实现废物利用,具有良好的社会效益和市场前景。A kind of self-leveling material utilize FGD gypsum was used as basic material,mixed with active aggregate and some accessory ingredients.The self-leveling material had an excellent property,flexural strength and compressive strength respectively reached to 6.8MPa and 29.2MPa,soft coefficient was up to 0.82.The performance were better than the standards of JC/T985-2005 and JC/T1023-2007,which would use waste and realize recycled economy.
