钢渣法烧结烟气脱硫石膏用于水泥生产的研究

Application of sintering gas desulfurization gypsum from steelmaking slag process in cement production

通过实验室小磨试验,研究了用钢渣法烧结烟气脱硫石膏作水泥缓凝剂对水泥性能的影响,并与天然石膏及电厂脱硫石膏进行了对比。结果表明,钢渣法烧结烟气脱硫石膏符合GB/T21371—2008要求,可用作水泥缓凝剂。

By means of testing mill test, the effects of sintering gas desulfurization gypsum, from steelmaking slag process, as cement retarder on the performance of cement were studied. Compared with the natural gypsum and desulfurized gypsum from power plant, the sintering gas desulfurization gypsum from steelmaking slag process could be used as cement retarder, and satisfied the regulation of GB/T21371-2008.
