High-wear-resistance anti-skid pavement aggregate, pavement and preparation method
The invention discloses a high-wear-resistance anti-skid pavement aggregate, a pavement and a preparation method. The high-wear-resistance anti-skid pavement aggregate is obtained by taking a waste refractory material as a raw material and carrying out sorting, crushing, screening, soaking and strengthening treatment on the waste refractory material, and the waste refractory material comprises a waste high-alumina refractory material and a waste silicon mullite brick. Main phases in the waste high-alumina refractory material are corundum, mullite and quartz, wherein the mass percentage of Al2O3 is greater than or equal to 60%; main phases in the waste silicon mullite brick are corundum, mullite, silicon carbide and quartz, wherein the mass percentage of Al2O3 is greater than or equal to 55%. The waste is high in alumina content, high in hardness and strength and good in wear resistance, and compared with a process of treating the waste to prepare a refractory material, the process is simple and low in cost.
本发明公开了一种高耐磨抗滑路面集料、路面及制备方法，所述的高耐磨抗滑路面集料以废旧耐火材料为原料，对废旧耐火材料拣选、破碎、筛分、浸泡及强化处理后得到，所述的废旧耐火材料为包括废旧高铝质耐火材料和废旧硅莫砖。所述的废旧高铝质耐火材料中主要物相为刚玉、莫来石和石英，其中AlO质量百分含量≥60％；所述的废旧硅莫砖中主要物相为刚玉、莫来石、碳化硅和石英，其中AlO质量百分含量≥55％。废料中氧化铝含量高、硬度强度高、耐磨性能较好，相比于将废料处理后用于制备耐火材料工艺简单、成本低。
