Phosphogypsum stabilizing material and application thereof
The invention relates to the technical field of ardealite resource utilization, in particular to an ardealite stabilizing material and application. The phosphogypsum stabilizing material provided by the invention comprises a natural aggregate, a phosphogypsum lightweight aggregate and a cementing material, the natural aggregate comprises a natural aggregate with the particle size of 0-4.75 mm and a natural aggregate with the particle size of 4.75-9.5 mm; the ardealite light aggregate comprises an ardealite light aggregate with the particle size of 9.5-19 mm and an ardealite light aggregate with the particle size of 19-31.5 mm; the mass ratio of the natural aggregate to the phosphogypsum lightweight aggregate to the cementing material is (40-50): (50-60): (7-11); the mass percentage content of ardealite in the ardealite lightweight aggregate is 80-90%, the cementing material is oversulfated ardealite slag cement, and the mass percentage content of ardealite in the oversulfated ardealite slag cement is 40-50%. According to the ardealite stabilizing material, large-doping-amount doping of the ardealite lightweight aggregate can be realized.
本发明涉及磷石膏资源化利用技术领域，尤其涉及一种磷石膏稳定材料及应用。本发明提供的磷石膏稳定材料，包括天然集料、磷石膏轻集料和胶凝材料；天然集料包括粒径为0～4.75mm的天然集料和粒径为4.75～9.5mm的天然集料；磷石膏轻集料包括粒径为9.5～19mm的磷石膏轻集料和粒径为19～31.5mm的磷石膏轻集料；天然集料、磷石膏轻集料和胶凝材料的质量比为(40～50)：(50～60)：(7～11)；磷石膏轻集料中磷石膏的质量百分含量为80～90％，胶凝材料为过硫磷石膏矿渣水泥，过硫磷石膏矿渣水泥中磷石膏的质量百分含量为40～50％。所述磷石膏稳定材料中可以实现磷石膏轻集料的大掺量掺杂。
