Cement-free roadbed material and preparation method thereof
The invention discloses a cement-free roadbed material and a preparation method thereof.The roadbed material is mainly prepared from blast furnace slag, steel slag, solid waste gypsum and tailing sand, and according to the preparation method of the cement-free roadbed material, the roadbed material is obtained through semi-dry extrusion forming or slurry pouring forming according to different water contents after the raw materials are mixed. The roadbed material with excellent mechanical strength is obtained by taking the solid waste material as the raw material, the resource utilization of the solid waste material is realized, the purpose of treating waste with waste is achieved, and the preparation method of the roadbed material has the advantages of wide raw material source, low cost, simple and convenient process and the like, and has higher economic value and environmental protection value.
本发明公开了一种无水泥路基材料及其制备方法，该路基材料主要原料为高炉矿渣、钢渣、固废石膏和尾矿砂，其制备方法根据原料混合后的含水率不同，采用半干挤压成型或浆体浇筑成型得到。本发明以固废材料为原料，获得力学强度优异的路基材料，实现固废材料的资源化利用，达到“以废治废”的目的，且路基材料的制备方法具有原料来源广泛、成本低廉、工艺简便等优点，具有较大的经济价值和环保价值。
