Alkali-free liquid accelerator for sprayed concrete and preparation method of alkali-free liquid accelerator
The invention provides an alkali-free liquid accelerator for sprayed concrete and a preparation method of the alkali-free liquid accelerator, and belongs to the technical field of accelerators. The sewage treatment agent is prepared from the following raw materials in parts by weight: 12-15 parts of magnesium fluosilicate, 3-5 parts of hydrogen fluoride, 5-7 parts of aluminum hydroxide, 20-30 parts of aluminum sulfate, 3-5 parts of an organic alcohol amine carboxylic acid polymer, 2-3 parts of organic acid, 1-2 parts of polyacrylamide and 20-30 parts of water. The alkali-free liquid accelerator for sprayed concrete has the advantages that the alkali-free liquid accelerator is small in corrosive damage to human bodies, high in early-stage strength and later-stage compressive strength ratio and free of adverse effects on concrete durability, the tackifying components can reduce the dust concentration and the rebound amount in the spraying process, the mixing amount is low, the price is low, stability is good, and the rapid setting effect is remarkable.
本发明提出了一种喷射混凝土用无碱液体速凝剂及其制备方法，属于速凝剂技术领域。由以下原料按重量份制备而成：氟硅酸镁12‑15份、氟化氢3‑5份、氢氧化铝5‑7份、硫酸铝20‑30份、有机醇胺羧酸聚合物3‑5份、有机酸2‑3份、聚丙烯酰胺1‑2份、水20‑30份。本发明制得的喷射混凝土用无碱液体速凝剂对人体腐蚀性损伤小、早期强度高和后期抗压强度比高、对混凝土耐久性无不良影响、增粘成分可降低喷射过程中的粉尘浓度和回弹量等优点，且掺量较低、价格经济、稳定性好、速凝效果显著。
