The invention relates to the field of solid waste recycling and the technical field of building material production, in particular to high-strength ardealite-based aggregate and a preparation method thereof. The preparation method of the high-strength ardealite-based aggregate comprises the following steps: adding water into cooked ardealite powder, and uniformly stirring to obtain wet ardealite powder; and carrying out compression molding on the wet gypsum powder, and demolding to obtain the phosphogypsum-based aggregate. According to the preparation method disclosed by the invention, only the cooked ardealite powder is used as a raw material, and inorganic cementing materials such as cement and slag are not required to be doped, so that the cost of auxiliary raw materials is reduced, the mixing treatment process among the raw materials is also reduced, and the raw material cost and the production cost are reduced.
本发明涉及固体废物资源化领域和建筑材料生产技术领域，尤其涉及一种高强度磷石膏基骨料及其制备方法。一种高强度磷石膏基骨料的制备方法，包括以下步骤：在熟磷石膏粉内加水，搅拌均匀后，得到湿润石膏粉；将湿润石膏粉压制成型，脱模，得到磷石膏基骨料。本发明制备方法的原材料仅为熟磷石膏粉，不需要掺加水泥、矿渣等无机胶凝材料，既减少的辅助原材料的成本，也减少的原料之间的混合处理工序，有利于降低原料成本和生产成本。
