磷石膏在新型墙体材料中的应用研究

摘要

The effect of impurities in phosphogypsum on its performance and its pretreatment are stated;the theoretical basis for production of gypsum products, concrete products and silicate concrete products, etc. new wall materials by utilization of phosphogypsum cement, and attention problems are analyzed.%　　简述了磷石膏中不同杂质对其应用性能的影响及其预处理方式；从石膏基本性质出发，分析了利用磷石膏生产石膏制品、水泥混凝土制品和硅酸盐混凝土制品类新型墙体材料的理论依据和需注意的问题；提出了利用磷石膏对粉煤灰、矿渣的硫酸盐激发作用生产混凝土实心砖、蒸压砖，应警惕延迟钙矾石膨胀对制品的危害。
