Road base material adopting pyrite tailings and preparation method of road base material
The invention discloses a road base material adopting pyrite tailings. The road base material comprises the following components in parts by mass: 10-40 parts of a novel unfired low-carbon cementing material curing agent, 60-90 parts of a stabilized material and water, the novel baking-free low-carbon cementing material curing agent comprises the following components in percentage by mass: 15-40% of steel slag powder, 40-70% of slag powder, 5-30% of byproduct gypsum and a special exciting agent, wherein the special exciting agent comprises the following components: sodium carbonate, sodium sulfate and/or sodium stearate; the stabilized material is pyrite tailings. The invention further discloses a preparation method of the roadbase material adopting the pyrite tailings. The preparation method has the beneficial effects that the dual theories of alkali excitation and sulfate excitation are utilized, the synergistic coupling excitation effect between solid wastes is fully exerted, a hydration hardening community is formed by the curing agent and the pyrite tailings, the prepared road base material is good in performance, and large-dosage and high-value utilization of the pyrite tailings is achieved.
本发明公开了一种采用硫铁矿尾矿的道路基层材料,该道路基层材料包括:新型免烧低碳胶凝材料固化剂10~40质量份,被稳定材料60~90质量份,和水;新型免烧低碳胶凝材料固化剂的组分和质量百分比包括:钢渣粉15%~40%、矿渣粉40%~70%、副产石膏5%~30%和专用激发剂,专用激发剂的组分包括碳酸钠、硫酸钠和/或硬脂酸钠;被稳定材料为硫铁矿尾矿。以及公开了一种采用硫铁矿尾矿的道路基层材料的制备方法。本发明的有益效果为:利用碱激发和硫酸盐激发双重理论,充分发挥固废间的协同耦合激发效应,实现固化剂与硫铁矿尾矿形成水化硬化共同体,制备出的道路基层材料性能良好,实现了硫铁矿尾矿的大掺量、高值化利用。
