| Abstract: | In this article,lead-zinc tailing was used as raw material to prepare middle heat clinker.The easiness of burning was tested by the differential scanning calorimetry(DSC).The content of clinker was determined by X-ray diffraction(XRD) and the shape of the silicates crystal was investigated by scanning electron microscope.The hydrating heating was tested by the isothermal calorimeter.The results show that using lead-zinc tailing to prepare cement clinker can reduce the eutectic point;the silicate crystal was well formed and the hydrating heat was accord with the standard. |
