Phosphogypsum-phosphorus slag-based environment-friendly mortar and preparation method thereof
The invention discloses ardealite-phosphorus slag-based environment-friendly mortar and a preparation method thereof, and the mortar is prepared from the following components in parts by weight: 25 to 40 parts of ardealite, 25 to 40 parts of phosphorus slag, 10 to 20 parts of micron-sized silicon-aluminum powder, 10 to 20 parts of cement, 40 to 60 parts of water, 150 to 450 parts of aggregate, 0.01 to 0.05 part of starch ether, 0.01 to 0.05 part of bacteriostatic agent, 0.05 to 0.1 part of alkali activator and 0.2 to 1 part of viscosity modifier. The method has the advantages that abundant and cheap solid waste resources such as ardealite and phosphorus slag are utilized; and secondly, the undisturbed phosphogypsum is simply treated at low cost by adopting a circulating heat drying technology, so that a gypsum product with certain gelling performance is obtained. And thirdly, the alkali excitation technology and the sulfate excitation technology cooperate to achieve a better use effect, and a retarder is not needed. And 4, the problem of mortar mildewing caused by organic matter impurities in the phosphogypsum product is solved by simultaneously doping the viscosity modifier and the bacteriostatic agent.
本发明公开了一种磷石膏‑磷渣基环保砂浆及其制备方法，砂浆重量份数的组分：磷石膏25‑40份、磷渣25‑40份、微米级硅铝质粉10‑20份、水泥10‑20份、水40‑60份、骨料150‑450份、淀粉醚0.01‑0.05份、抑菌剂0.01‑0.05份、碱激发剂0.05‑0.1、黏度调节剂0.2‑1份，效果一是利用丰富廉价的磷石膏磷渣等固废资源。二是采用循环热烘技术将原状磷石膏进行低成本简单处理，得到具备一定胶凝性能的石膏产品。三是碱激发技术和硫酸盐激发技术协同反应达到更好的使用效果，且不需要缓凝剂。四是同时通过黏度调节剂和抑菌剂的掺入解决了磷石膏产品中有机质杂质导致的砂浆发霉的问题。
