摘　　要：研究了不同化学激发剂在不同掺量下对磷渣粉水化活性的影响,并通过XRD检测技术对磷渣粉料浆水化28 d后的矿物组成进行分析。实验结果表明:不同化学激发剂对磷渣粉水化活性有较大的影响。以10%Na2SO4为激发剂时(按磷渣粉质量比计),磷渣粉具有较好的水化活性,且磷渣粉料浆的初凝时间3.0 h,终凝时间6.0 h,28 d抗压强度37.5 MPa,水化活性指数1.45。The influence of the different dosage of chemical activators on hydration activity of phosphorus slag powder was studied,and the XRD testing technology was used to analyze the sclerotium crystallography constitute of the phosphorus slag powder slurry which have hydrated for 28 days in the certain curing condition.The results show that the different chemical activator has a significant influence on hydration activity of the phosphorus slag powder.When 10% Na2SO4（by weight of phosphorus slag powder） is used as the activator of phosphorous slag powder,hydration activity of the phosphorus slag powder is the best,and the properties of the slurry are as follows,initial setting time 3.0 h,final setting time 6.0 h,28 days compressive strength 37.5 MPa,and hydration activity index 1.45.
