Phosphogypsum lightweight building block and preparation method thereof
The invention provides a phosphogypsum lightweight building block and a preparation method thereof, and belongs to the technical field of building materials. The preparation method comprises the following steps: mixing alpha high-strength phosphogypsum, fly ash, steel slag and mineral powder to obtain a dry material; mixing the dry material, water, a water reducing agent, foam liquid and building rubber powder to obtain slurry; and pouring the slurry to obtain the phosphogypsum lightweight building block. The ardealite building block capable of effectively reducing radioactivity and radon precipitation amount is created for the first time, the steel slag, the mineral powder and the building rubber powder are reasonably utilized, contribution is made to environmental protection on the premise that mechanical properties are not affected, and the steel slag and the mineral powder have a certain protection effect on radon and radioactive pollutants and serve as radon-proof and radiation-proof materials, so that the ardealite building block has a good application prospect. The ardealite has the advantages that the radioactivity of the ardealite can be effectively reduced, the building rubber powder serves as an organic material to form a net-shaped covering layer on the surface, although the covering layer cannot completely absorb and resist radioactive rays, the number of gaps where radon overflows can be effectively reduced, and the radon overflowed from the inside can be well blocked.
本发明提供了一种磷石膏轻质砌块及其制备方法，属于建筑材料技术领域。本发明将α高强磷石膏、粉煤灰、钢渣和矿粉混合，得到干料；将干料、水、减水剂、泡沫液和建筑胶粉混合，得到浆料；将浆料进行浇筑，得到所述磷石膏轻质砌块。本发明首创了有效减少放射性和氡析出量的磷石膏砌块，合理利用钢渣、矿粉和建筑胶粉，在不影响力学性能的前提下，为环境保护事业做出贡献，钢渣和矿粉对氡和放射性污染物有一定的防护效果，作为防氡防辐射的材料，能够有效降低磷石膏的放射性，建筑胶粉作为有机材料在表面形成一层网状的覆盖层，这种覆盖层虽不能完全吸收抵抗放射性射线，但是可有效减少氡溢出的空隙数量，对内部溢出的氡有较好的阻挡作用。
