The invention relates to the field of solid waste recycling and the technical field of building material production, in particular to a method for producing gypsum blocks by utilizing phosphogypsum. The invention relates to a method for producing a gypsum block by utilizing ardealite, which comprises the following steps of: preparing wet gypsum powder from cooked ardealite powder, pressing to obtain a gypsum block green body, and naturally curing the gypsum block green body to obtain the gypsum block. According to the method, phosphogypsum is used as a unique raw material, on the premise that other auxiliary raw materials and chemicals are not doped, only water accounting for 15-20% of the mass of phosphogypsum needs to be doped, and the gypsum block which is high in strength and does not need to be aired and dried is produced by adopting a compression molding production method, so that the production difficulty of raw material preparation and mixing is reduced, the product airing link is omitted, and the production cost is reduced. The product production period is shortened, and the product mechanical strength is improved.
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,尤其涉及一种利用磷石膏生产石膏砌块的方法。一种利用磷石膏生产石膏砌块的方法,包括以下步骤:将熟磷石膏粉制备成湿润石膏粉后,压制,制得石膏砌块坯体,将石膏砌块坯体自然养护后,得到石膏砌块。本发明所述方法利用磷石膏作为唯一原料,不掺加其他辅助原料和药剂的前提下,仅需掺加磷石膏质量的15~20%水,采用压制成型生产方法,生产出强度高、不需要晾晒干燥的石膏砌块,从而降低原料配制、混合的生产难度,省却产品晾晒环节,缩短产品生产周期,并提高产品机械强度。
