摘　　要：以北京密云铁矿尾矿为原料,采用机械力化学方法对其进行活化,并采用粒度分析、X射线衍射(XRD)、扫描电子显微镜(SEM)及红外光谱(IR)分析机械力化学效应对尾矿活性的影响.以铁尾矿为主要原料制备出抗压强度达到89MPa、尾矿总体掺量达到70%的尾矿高强结构材料.Miyun iron ore tailings in Beijing were activated by a mechanochemical method.The influence of mechanochemical effect on the activation of the iron ore tailings was analyzed by means of grain size analysis,X-ray diffraction（XRD）,scanning electron microscope（SEM）and infrared radiation（IR）technologies.The iron ore tailings as raw materials were used to produce high-strength construction materials.It is shown that the compressive strength of the produced construction materials in which the overall content of the iron ore tailings is 70% can reach up to 89 MPa.
