摘　　要：烟气脱硫石膏是燃煤电厂采用石灰湿法脱硫产生的一种固体废弃物,将脱硫石膏用作水泥缓凝剂,掺入到水泥中,制备出满足工程要求的新材料,通过成球处理和去除所含杂质,更好地发挥脱硫石膏的作用,解决了目前脱硫石膏的利用问题,减少其对环境的影响,还可以降低水泥成本,产生一定的经济效益。Flue gas desulfurization gypsum is a solid waste with wet lime desulfurization method of coal-fired power plant desulfurization gypsum produced,will be used as cement retarder,mixed into cement,then the new materials which can meet the requirements of the project are produced. Through the ball handling and removal of impurities,the role of desulfurization gypsum can be played better,the using problem of the desulfurization gypsum at present is solved,too,their impact on the environment is reduced,but also can reduce the cost of cement,have a certain economic benefit.
