Impermeable alkali-free accelerator and preparation method thereof
The invention discloses an anti-permeability alkali-free accelerator, which is prepared from the following raw materials in percentage by weight: 40 to 50 percent of polyaluminum sulfate, 15 to 20 percent of aluminum hydroxide sol, 2 to 5 percent of hydrated magnesium silicate, 0.5 to 0.9 percent of inorganic acid, 3 to 5 percent of triethanolamine, 1 to 2 percent of glycolic acid, 0.8 to 1.5 percent of malic acid, 2 to 4 percent of nano silicon dioxide and the balance of water. The alkali-free setting accelerator has the beneficial effects that the prepared alkali-free setting accelerator is alkali-free and free of pungent smell, the corrosion effect on concrete and reinforcing steel bars caused by introduction of alkaline substances is effectively avoided, and meanwhile, the alkali-free setting accelerator has the characteristics of low mixing amount, low rebound resilience and excellent impermeability.
本发明公开了一种抗渗性无碱速凝剂，包括按重量百分比计的如下原料：聚合硫酸铝40％‑50％、氢氧化铝溶胶15‑20％、水合硅酸镁2％‑5％、无机酸0.5％‑0.9％、三乙醇胺3％‑5％、羟基乙酸1％‑2％、苹果酸0.8％‑1.5％、纳米二氧化硅2％‑4％，余量为水。本发明的有益效果在于：本发明制备的无碱速凝剂无碱、无刺激性气味，有效避免了因引入碱性物质对混凝土及钢筋造成的腐蚀作用，同时其具有掺量低，回弹性低、抗渗性能优异的特点。
