Cement steel slag micropowder stabilized steel slag macadam semi-rigid base and preparation method thereof
The invention discloses a cement steel slag micropowder stabilized steel slag macadam semi-rigid base and a preparation method thereof. The cement steel slag micropowder stabilized steel slag macadam semi-rigid base comprises the following raw material components in percentage by mass: 4.0%-6.0% of a composite gelling agent, M1 * 5.0%-M1 * 10.0% of steel slag sand, M2 * 15.0%-M2 * 25% of steel slag aggregate, 16.0%-21.0% of machine-made sand and 49.0%-59.0% of macadam. The cement steel slag micropowder stabilized steel slag macadam semi-rigid base prepared by the invention has the characteristics of convenience in material taking, energy conservation and environmental protection; according to the material, a large amount of the steel slag micro powder, the steel slag sand and the steel slag aggregate can be utilized, the problems of environmental pollution and land resource occupation caused by steel slag stockpiling are solved, the increasingly-short admixture and gravel resources can be relieved, and the unconfined compressive strength of the prepared cement steel slag micro powder stabilized steel slag macadam semi-rigid base meets the standard requirement and is suitable for large-scale popularization and application. And the production cost of the semi-rigid base layer can be saved.
本发明公开了一种水泥钢渣微粉稳定钢渣碎石半刚性基层及其制备方法，包括以下质量含量的各原料组分：4.0%~6.0%的复合胶凝剂、M1×5.0%~M1×10.0%的钢渣砂、M2×15.0%~M2×25%的钢渣骨料、16.0%~21.0%的机制砂、49.0%~59.0%的碎石。本发明制备的水泥钢渣微粉稳定钢渣碎石半刚性基层具有取材便利、节能环保的特点；该材料可大量利用钢渣微粉、钢渣砂和钢渣骨料，解决钢渣堆存引发的环境污染及占用土地资源的问题，也可以缓解日益短缺的掺合料、砂石资源，本发明制备得到的水泥钢渣微粉稳定钢渣碎石半刚性基层的无侧限抗压强度满足规范要求，且能节约半刚性基层的生产成本。
