Abstract

Abstract

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.
