水泥稳定磷渣碎石基层材料的研究

A Study on Basecourse of Cement Stabilizing Phosphorous Slag and Gravel

研究探讨了用磷渣取代石屑 ,配制符合级配要求的集料 ,用水泥稳定作路面基层材料的可行性。结果表明 :用磷渣取代石屑配制的水泥稳定材料强度提高了 7%～ 2 5 % ,最大干密度降低约 5 %。水泥稳定磷渣碎石基层路用性能好 ,在磷渣资源丰富的地区 。

In this paper the feasibility of using phosphorous slag which replaces stone chips as the aggregate of basecourse is studied. The strength of basecourse in which phosphorous slag are used instead of stone chips as aggregates is increased by 7%～25%, while its maximum density is reduced by 5%. The basecourse of cement stabilizing phosphorous slag and gravel has good characters, it has good perspective for application in areas with abundant phosphorous slag.
