Phosphoric acid excited magnesium-rich nickel slag geopolymer cementing material and preparation method thereof
The invention discloses a phosphoric acid excited magnesium-rich nickel slag geopolymer cementing material and a preparation method thereof. The cementing material is composed of magnesium-rich nickel slag and fly ash, and the cementing material is mainly composed of, by weight, 50-90 parts of magnesium-rich nickel slag, 50-10 parts of fly ash, 10-20 parts of phosphoric acid, and 20-40 parts of water. The magnesium-rich nickel slag with complex components and the fly ash can be directly used for preparing the cementing material, the cementing material with excellent comprehensive performances such as compressive strength is finally obtained by controlling the ratio of the raw materials, and the cementing material can be used as an admixture of cement and can also be used as a cementing material of concrete. According to the invention, the solid waste cementing material excited by acid is utilized, and the method has the advantages of simple processing technology, environmental protection, low energy consumption and low cost, and can show better compressive strength.
本发明公开了一种磷酸激发富镁镍渣地质聚合物胶凝材料及制备方法，包括：由富镁镍渣和粉煤灰组成的胶凝材料，主要由以下成分组成：按重量份计，富镁镍渣50‑90份，粉煤灰50‑10份，磷酸10‑20份，水20‑40份，明能够将成分复杂的富镁镍渣、粉煤灰直接用于制备胶凝材料，通过控制各原料的配比最终得到抗压强度等综合性能优异的凝胶材料，可用作水泥的掺和料，也可用作混凝土的胶结料。根据本发明，利用酸激发的固废胶凝材料，且加工工艺简单、绿色环保、能耗低、成本低的方法，可显示出较好的抗压强度。
