The invention discloses an alkali-free liquid accelerator prepared from aluminum hydroxide gel waste residues. The alkali-free liquid accelerator is prepared from the following raw materials: 9-25 parts of hydrofluoric acid, 2-7 parts of aluminum hydroxide, 1-4 parts of aluminum hydroxide gel waste residues, 14-45 parts of deionized water, 0.5-1.5 parts of magnesium fluosilicate, 3-6 parts of liquid caustic soda and 0.5-2 parts of triethanolamine. The liquid accelerator which is good in cement adaptability and can be widely applied to various types of cement is prepared by selecting the doping proportion of the aluminum hydroxide gel waste residues, selecting raw materials for preparing the alkali-free liquid accelerator and controlling the synthesis proportion of all the materials.
本发明公开了一种利用氢氧化铝凝胶废渣制备的无碱液体速凝剂，本无碱液体速凝剂由以下原料制成：氢氟酸9‑25份、氢氧化铝2‑7份、氢氧化铝凝胶废渣1‑4份、去离子水14‑45份、氟硅酸镁0.5‑1.5份、液碱3‑6份、三乙醇胺0.5‑2份。本发明通过氢氧化铝凝胶废渣掺用比例、制备无碱液体速凝剂原料的选取、各物料合成比例的控制，制备出了一种对水泥适应性好，可广泛应用于各种水泥中的液体速凝剂。
