Preparation method of gypsum baking-free brick
The invention relates to the technical field of building materials, in particular to a preparation method of a gypsum baking-free brick. The preparation method comprises the following steps: preparingand uniformly mixing phosphogypsum, yellow sand, cement, lime and other raw material crystals, carrying out compression molding to obtain a baking-free brick blank, drying and dehydrating the baking-free brick blank at 120-180 DEG C to obtain a baking-free brick dry blank, and immersing the baking-free brick dry blank in room-temperature water to obtain the gypsum baking-free brick. According tothe method, a large amount of process solid waste phosphogypsum can be consumed, environmental pollution caused by phosphogypsum is avoided, waste is turned into wealth, cyclic utilization of resources is achieved, the baking-free brick serving as a building wall material is prepared, and an effective recycling way is provided for solving the problem of pollution caused by phosphogypsum. Therefore, the gypsum baking-free brick has relatively economic, social and environmental benefits.
本发明涉及建筑材料技术领域，具体涉及一种石膏免烧砖的制备方法。制备方法为磷石膏、黄沙、水泥和石灰等原料晶配置和混合均匀，压制成型为免烧砖坯体，然后将免烧砖坯体置于120~180℃的温度下干燥脱水，制得免烧砖干坯，接着将免烧砖干坯浸于室温水中，制得石膏免烧砖。本发明不仅能够大量消耗工艺固体废物磷石膏，解决磷石膏造成的环境污染，同时变废为宝，实现资源的循环利用，制备出建筑墙体材料——免烧砖，为解决磷石膏造成污染问题提供了一条有效的资源化途径。因此，石膏免烧砖具有较的经济、社会和环境效益。
