Preparation method of Bayer process red mud roadbed material
The invention provides a preparation method of a Bayer process red mud roadbed material, aims to solve the technical problems of high cost and poor economic benefit of the red mud roadbed material, and belongs to the field of light metal metallurgy, and the preparation method comprises the following steps: mixing and stirring Bayer process filter-pressed red mud, a water-absorbing auxiliary agent and a stabilizing auxiliary agent to obtain red mud modified soil; mixing and stirring the red mud modified soil, a promoting auxiliary agent and an adjusting auxiliary agent to obtain the Bayer process red mud roadbed material, wherein the ratio of the mass of the water absorption aid to the mass of the stabilizing aid to the mass of the promoting aid to the mass of the adjusting aid to the solid content of the Bayer process filter pressing red mud is (1-30): (1-400): (1-20): (0.01-0.5): (100). According to the method, Bayer process filter-pressed red mud is used as a raw material to prepare the roadbed material, the cost of the red mud roadbed material can be effectively reduced, and economic benefits are improved.
本发明提供了一种拜尔法赤泥路基材料的制备方法，以解决赤泥路基材料成本高、经济效益差的技术问题，属于轻金属冶金领域，包括：将拜耳法压滤赤泥、吸水助剂和稳定助剂进行混合搅拌，获得赤泥改性土；将所述赤泥改性土、促进助剂和调整助剂进行混合搅拌，获得拜耳法赤泥路基材料；其中，所述吸水助剂、所述稳定助剂、所述促进助剂和所述调整助剂的质量与所述拜耳法压滤赤泥的固含量之比为(1～30)∶(1～400)∶(1～20)∶(0.01～0.5)∶(100)。该方法以拜耳法压滤赤泥为原料制备路基材料，能够有效降低赤泥路基材料成本，提升经济效益。
