摘　　要：随着循环流化床锅炉脱硫技术的发展,大量的固硫渣被堆存。固硫渣含有大量的f-Ca O和SO3,通过对固硫渣中f-Ca O含量和消解速度的研究,测试其作为水泥混合材和混凝土砖骨料制品时的安定性。结果表明:固硫渣中大部分f-Ca O容易消解,经淋水处理以后不会对安定性产生不良影响,可用于水泥混合材和混凝土砖骨料。With the development of desulfurization technology for circulating, fluidized bed boiler, large amounts of desulfurization slag is stored up. Desulfurization slag contains a lot of f-CaO and SO3, through the study of the content and digestion rate of f-CaO in desulfurization slag, and the test of the stability of the slag as a cement admixture and aggregate for concrete brick. The test shows that most f-CaO can be easily digested, and can＇ t affect the stability after the watering process, so that the slag can be used as mixture and aggregate for concrete brick.
