摘　　要：针对磷渣粉缓凝和初期活性指数低的特点,对其进行了粉磨和浸泡并测试了处理前后的凝结时间和初期活性指数,结果表明:浸泡可以抑制缓凝效果并提升1 d活性指数,但对3 d、7 d活性指数的影响有限;经粉磨及浸泡综合处理后,相同粉磨时间的磷渣粉3 d、7 d活性指数的最大增长幅度可达7%、17%;浸泡后,磷渣粉颗粒表面的氟、磷元素减少。According to the characteristics of long setting time and low initial strength activity index(SAI)of ground granulated phosphorus slag(GGPS),GGPS was further ground and immersed,and then,the setting time and initial strength activity index of GGPS before and after treatment were tested.The results show that immersing can significantly reduce the retardation of GGPS and increase the 1 d activity index,but has little effect on 3d and 7d SAI.However,by the comprehensive treatment of grinding and immersing,the maximum increases of 3d and 7d SAI of GGPS with the same grinding time can reach 7%and 17%respectively.After immersing,the content of fluorine and phosphorus elements on the surface of GGPS particles decreased.
