Composite solid waste pavement base binder and preparation method thereof
The invention discloses a composite solid waste pavement base binder and a preparation method thereof, and belongs to the technical field of road engineering. The composite solid waste pavement base binder is prepared by mixing pretreated alkaline ardealite powder, fly ash, slag powder and cement. The industrial waste phosphogypsum slurry raw material is subjected to alkaline pretreatment to obtain the alkaline phosphogypsum powder, the alkaline phosphogypsum powder is mixed with the solid waste such as the fly ash and the slag and the cement, and the mixture is applied to a semi-rigid base material to be used as a gelling binder, so that an effective utilization way of the industrial waste residue material is provided, and the utilization rate of the industrial waste residue material is increased. Moreover, the resource utilization rate of industrial waste residue materials can be increased, and the problem of environmental pollution caused by stockpiling and discharging of industrial waste residues is solved. And the prepared pavement base binder can improve the strength of the pavement base, reduce the shrinkage cracking effect of the pavement base, reduce the cement consumption, reduce the cost, and achieve the purposes of recycling solid wastes, and being economical and environment-friendly.
本发明公开了一种复合固体废弃物路面基层结合料及其制备方法，属于道路工程技术领域。该复合固体废弃物路面基层结合料由经过预处理的碱性磷石膏粉与粉煤灰、矿渣粉和水泥混合而成。本发明通过将工业废料磷石膏浆体原料进行碱性预处理，得到碱性磷石膏粉后再与粉煤灰、矿渣等固体废弃物以及水泥混合，应用于半刚性基层材料中作为胶凝结合料使用，不仅提供工业废渣材料的有效利用途径，而且还可以提高工业废渣材料的资源利用率，解决工业废渣的堆存和排放造成环境污染问题。并且本申请制备的路面基层结合料能提高路面基层强度、减少路面基层收缩开裂效果，同时减少水泥用量，降低成本，达到固体废弃物循环利用、经济环保的目的。
