High-fluidity red mud slag geopolymer grouting material and preparation method thereof
The invention relates to a high-fluidity red mud slag geopolymer grouting material and a preparation method thereof. The grouting material is composed of red mud, slag, waste glass powder, a naphthalene water reducer and a sodium hydroxide alkaline activator. The water-binder ratio of the grouting material is 0.6-1.0. The preparation method comprises the following steps: mixing and uniformly stirring the red mud, the slag and the waste glass powder in parts by mass to obtain a sizing material component A; sodium hydroxide is dissolved in water, the concentration is controlled to be 2 mol/L, an alkaline exciting agent is formed, a naphthalene water reducer is dissolved in the alkaline exciting agent according to the mass part, and an additive component B is obtained; adding the rubber component A into the additive component B, and controlling the water-rubber ratio to be 0.6-1.0. The red mud, the slag, the waste glass and other wastes are used, the wastes are turned into wealth, and the naphthyl water reducer is added, so that the flowability and the mechanical property of the geopolymer grouting material are effectively improved.
本发明是一种高流动性赤泥矿渣地聚物灌浆材料及制备方法，灌浆材料由赤泥、矿渣、废玻璃粉、萘系减水剂、氢氧化钠碱性激发剂组成；灌浆材料的水胶比为0.6‑1.0。制备时：将赤泥、矿渣、废玻璃粉按照质量份数混合并搅拌均匀，得到胶料组分A；将氢氧化钠溶解于水中，控制浓度为2mol/L，形成碱性激发剂，将萘系减水剂按照质量份数溶解于碱性激发剂中，得到添加剂组分B；将胶料组分A加入添加剂组分B中，控制水胶比为0.6‑1.0。本发明使用赤泥、矿渣、废玻璃等废弃物，变废为宝，加入萘基减水剂有效地增加了地聚物灌浆料的流动性和力学性能。
