Cement-lime-ardealite cured red mud road base mixture and preparation method thereof
The invention discloses a cement-lime-ardealite cured red mud roadbase mixture and a preparation method thereof, cement, lime and ardealite are used as a mixed curing agent to synergistically cure red mud, and the red mud obtained by curing treatment is used as a highway pavement base material. According to the maximum dry density and the optimal water content of the mixture and the construction process of the existing road base mixture, the pavement base can be obtained after uniform mixing, compaction and leveling; the cured red mud is applied to highway pavement base filling, so that a large amount of red mud solid waste is recycled, and the method has important social value and significance for reducing occupation of scarce land resources caused by industrial waste accumulation, reducing environmental pollution hazards and saving highway engineering construction cost. The road base mixture has good strength and durability and economic benefits, the preparation process of the road base mixture is simple, the raw materials are easy to obtain, and the road base mixture is convenient to popularize and apply in engineering practice.
本申请公开了一种水泥‑石灰‑磷石膏固化赤泥道路基层混合料及其制备方法，以水泥、石灰、磷石膏为混合固化剂协同固化赤泥，固化处理得到的赤泥作为公路路面基层材料，根据混合料最大干密度和最佳含水率以及既有道路基层混合料施工工艺，经均匀拌合和压实整平后可得到路面基层；将固化处理后的赤泥应用于公路路面基层填筑中，使得大宗赤泥固体废料资源化利用，对于减少工业废料堆积对紧缺土地资源的占用和降低环境污染危害，节约公路工程建设成本具有重要社会价值和意义，所采用的固化剂掺量较少，具备良好的强度和耐久性能且兼具经济效益，该道路基层混合料制备工艺简单，原料易于获取，便于工程实际中推广应用。
