Iron tailing-based soil improvement material and preparation method thereof

The invention relates to an iron tailing-based soil improvement material and a preparation method thereof, and the preparation method comprises the following steps: (1) mixing iron tailing powder, a pore forming agent, a foaming agent, a binder, a sintering aid and a solvent to obtain mixed slurry; (2) drying the mixed slurry obtained in the step (1) to obtain a green body; and sintering the obtained green body to obtain the iron tailing-based soil improvement material. By adopting a composite pore-forming process of a pore-forming agent adding method and a mixed foaming method, the prepared iron tailing-based soil improvement material has the characteristics of high aperture ratio, good water absorption, good water retention effect and good air permeability, meanwhile, the total amount of additives is small, the preparation time is short, the production efficiency is improved, the production cost is reduced, and the method is suitable for industrial production. And scale treatment of the iron tailings can be
