Preparation method of roadbed early strength cementing material
The invention belongs to the field of roadbed materials, and discloses a roadbed early strength cementing material and a preparation method thereof. The preparation method comprises the following steps: firstly pretreating phosphogypsum and phosphate tailings, then mixing the pretreated phosphate tailings and fly ash to prepare a braised material, then reasonably proportioning the pretreated phosphogypsum and the braised material, finally adding an alkaline calcium activator, an adhesive, a water reducing agent and water, uniformly mixing, and molding to obtain the roadbed early strength cementing material. The method is easy and convenient to operate, low in cost, environmentally friendly and capable of enhancing resource recycling, and the material is high in early strength and good in hydraulicity, can meet the road requirement of first-grade roads, has large social benefits and economic benefits and is suitable for application and popularization.
本发明属于路基材料领域，公开了一种路基早强胶凝材料及其制备方法。本发明首先对磷石膏、磷尾矿进行预处理，然后将预处理后的磷尾矿和粉煤灰混合制备焖料，接着将预处理后磷石膏、焖料进行合理配比，最后添加碱性钙质激发剂、胶粘剂、减水剂和水混合均匀，成型即得路基早强胶凝材料。本发明不仅操作简便、成本低、环保、增强资源循环利用，而且材料早期强度高、水硬性好，能满足一级公路的路用要求，具有较大社会效益及经济效益，适合推广应用。
