Mineral powder for asphalt concrete as well as preparation method and application of mineral powder
The invention relates to the technical field of concrete, in particular to mineral powder for asphalt concrete as well as a preparation method and application of the mineral powder. The mineral powder for the asphalt concrete comprises the following components: at least one substance selected from green mud and white mud, fly ash, slag and waste ore powder, wherein a weight ratio of the at least one substance from the green mud and the white mud is 50-80%, and the balance is a mixture of the fly ash, the slag and the waste ore powder. The preparation method of the mineral powder for the asphalt concrete comprises the following steps: S101, drying at least one substance selected from the green mud and white mud until a water content is lower than 3%; and S102, adding the fly ash, the slag and the waste ore powder into the substance dried in the step S101, carrying out mixing, and pouring the mixture into a flour mill for milling after mixing to obtain ore powder. By adopting the above technical scheme, the problem that the environment is polluted in existing treatment processes of the green mud and the white mud is solved, and the green mud and the white mud can be turned into wealth and are used for preparing the mineral powder for the asphalt concrete.
本发明涉及混凝土的技术领域，具体涉及一种沥青混凝土用矿粉及其制备方法和应用。一种沥青混凝土用矿粉，包括以下组分：绿泥或白泥中的至少一种物质、粉煤灰、炉渣和废矿石粉末，所述绿泥或白泥中至少一种的重量占比为50～80％，其余为所述粉煤灰、炉渣和废矿石粉末的混合物。所述沥青混凝土用矿粉的制备方法，包括：S101、将绿泥或白泥中的至少一种物质干燥至含水率低于3％；S102、向S101干燥后的物质中加入粉煤灰、炉渣和废矿石粉末，并将其混合，混合后将混合物倒入磨粉机中进行碾磨制得矿粉。采用本技术方案克服了现有的绿泥和白泥在处理过程中对环境造成污染的问题，可将绿泥和白泥变废为宝，用于制备沥青混凝土用矿粉。
