Reinforced recycled aggregate, preparation method thereof and application of reinforced recycled aggregate in solid waste stabilized macadam base
The invention discloses a reinforced recycled aggregate, a preparation method thereof and application of the reinforced recycled aggregate in a solid waste stabilized macadam base, and belongs to the technical field of building materials. Carrying out ball milling, heating and shaping on the recycled aggregate to obtain shaped recycled aggregate and recycled micro powder; mixing the regenerated micro powder with a nano material and a filling material, and then carrying out ball milling treatment to obtain activated regenerated micro powder; mixing an alkaline solid waste activator, a precursor material and the activated and regenerated micro powder, and performing ball milling to obtain a solid waste cementing material; and mixing the solid waste cementing material with water to obtain solid waste cementing material mixed slurry, and coating the reshaped recycled aggregate with the slurry to obtain the reinforced recycled aggregate for preparing the stable macadam base. Through ball milling shaping and slurry wrapping treatment, old mortar attached to the surface of the recycled aggregate is effectively removed, the number of edges and corners is reduced, the porosity is reduced, the problems of high porosity, high water absorption, low apparent density and the like of the recycled aggregate are solved, and the mechanical property of the recycled aggregate is improved, so that the recycled aggregate can be used for preparing a stable macadam base.
本发明公开了一种强化再生骨料及其制备方法与在固废稳定碎石基层中的应用，属于建筑材料技术领域。将再生骨料球磨加热整形，得到整形再生骨料和再生微粉；将再生微粉与纳米材料、填充料混合后球磨处理，得到活化再生微粉；将碱性固废激发剂、前驱体材料、活化再生微粉混合后球磨，得到固废胶凝材料；将所述固废胶凝材料与水混合，得到固废胶凝材料混合料浆，使用该料浆对整形再生骨料进行裹浆，得到可用于制备稳定碎石基层的强化再生骨料。本发明通过球磨整形以及裹浆处理，有效去除了再生骨料表面附着的旧砂浆，并减少棱角数量，降低了孔隙率，解决了再生骨料高孔隙率、高吸水率、低表观密度等问题，提高了其力学性能，从而可以用于制备稳定碎石基层。
