摘要: 通过配料和烧制试验研究,成功地完成了掺加铁尾矿烧制胶凝材料的试验研究并取得突破。与GB/175—2007通用硅酸盐水泥标准对照,铁尾矿掺量为6%的胶凝材料强度达到了52.5硅酸盐水泥标准;铁尾矿掺量为10%的胶凝材料的强度达到了42.5R硅酸盐水泥标准;铁尾矿掺量为15%的胶凝材料强度达到了32.5硅酸盐类水泥的标准。对试样的XRD,SEM和能谱分析研究结果表明,利用铁尾矿烧制的胶凝材料具有与普通硅酸盐水泥熟料相似的矿物组成。

Abstract: Based on the experimental study on the ingredients and firing,the firing tests of cementing materials with mixture of iron tailings has been successfully completed and a breakthrough is obtained.According to the GB/175-2007 standard of common portland cement,the cementing material sample with addition of 6% iron tailings has got the strength that is equal to 52.5# portland cement; the cementing material sample with addition of 10% iron tailings has got the strength that is equal to 42.5R portland cement; and the cementing material sample with addition of 10% iron tailings has got the strength that is equal to 32.5 portland cement.XRD,SEM and EDS testing results on the samples show that the cementing material fired with iron ore tailings have a similar mineral composition to the clinker aggregate of Portland cement.
