Low-dosage high-early-strength alkali-free liquid accelerator and preparation method thereof
The invention discloses a low-dosage high-early-strength alkali-free liquid accelerator and a preparation method thereof. The alkali-free liquid accelerator is prepared from the following raw materials: 1, an alkali-free liquid accelerator; 50%-60% of modified aluminum sulfate, 2%-4% of a fluorine-aluminum complex solution, 3%-6% of an organic cosolvent, 1%-2% of a pH regulator, 0.5%-1.5% of an inorganic stabilizer, 0.3%-0.5% of a viscosity regulator, 4%-6% of a composite early strength agent and the balance of water, wherein the sum of the mass percentages of the components is 100%. The invention also provides a preparation method of the alkali-free liquid accelerator. The preparation process of the alkali-free liquid accelerator is simple; hydrofluoric acid-free process, alkali-free, chlorine-free, rust-free steel bar, non-polluting environment. Meanwhile, when the mixing amount of the alkali-free liquid accelerator is 5%-6%, the technical requirements of GB/T35159-2017 on the alkali-free accelerator can be met, the one-day compressive strength is larger than or equal to 13.0 MPa, and the alkali-free liquid accelerator has the advantages of being low in mixing amount, good in stability, high in early strength and large in later strength retention rate.
一种低掺量高早强型无碱液体速凝剂及其制备方法，无碱液体速凝剂是由下述原料制成的：改性硫酸铝50％～60％，氟铝络合物溶液2％～4％，有机助溶剂3％～6％，pH调节剂1％～2％，无机稳定剂0.5％～1.5％，粘度调节剂0.3％～0.5％，复合早强剂4％～6％，余量为水，上述各组分的质量百分比之和为100％。本发明还提供了所述无碱液体速凝剂的制备方法。该无碱液体速凝剂制备工艺简单，不含氢氟酸，无碱、无氯，不锈蚀钢筋，不污染环境，不伤害作业人员的身体，同时该无碱液体速凝剂掺量为5％～6％时即能满足GB/T35159‑2017对无碱速凝剂的技术要求，1天抗压强度≥13.0MPa，具有掺量低、稳定性好、早期强度高、后期强度保留率大的特点。
