Water-resistant undisturbed phosphogypsum-magnesium-rich slag cementing material
The invention discloses a water-resistant undisturbed phosphogypsum-magnesium-rich slag cementing material, solves the problem of accumulation of a large amount of phosphogypsum, prevents secondary environmental pollution, and solves the problems of low cementing activity of undisturbed phosphogypsum, limited reutilization range of phosphogypsum in the building field, and poor water resistance of phosphogypsum mortar. The invention provides a way with higher additional value for treating a large amount of phosphogypsum, and can also partially replace cement to be applied to the building industry. The water-resistant undisturbed phosphogypsum-magnesium-rich slag cementing material is prepared from the following components in percentage by mass: 10 to 20 percent of undisturbed phosphogypsum, 10 to 20 percent of a water-resistant reinforcing material and 70 to 80 percent of magnesium-rich slag.
本发明公开了一种耐水性原状磷石膏‑富镁矿渣胶凝材料，解决了大量堆积磷石膏问题的同时防止二次环境污染问题，并且解决了原状磷石膏胶凝活性低，在建筑领域对磷石膏的再利用范围有限，磷石膏砂浆耐水性较差的问题。为大量处理磷石膏提供了一条附加值较高的途径，也可部分替代水泥应用在建筑行业。本发明的耐水性原状磷石膏‑富镁矿渣胶凝材料，其是由以下质量百分比的各组分组成：原状磷石膏10‑20％、耐水增强材料10‑20％、富镁矿渣70‑80％。
