Concrete liquid accelerator
The invention discloses a concrete liquid accelerator, and relates to the technical field of liquid accelerators. The preparation method comprises the following specific preparation steps of: 1, respectively weighing the following raw materials by weight: 30% of aluminum hydroxide, 20% of magnesium hydroxide, 50% of aluminum sulfate, 35% of a hydrofluoric acid solution, 25% of fluosilicic acid, 1.8% of an additive, 0.8% of a stabilizer and 10.5% of a dispersion enhancer; 2, mixing the aluminum hydroxide and the magnesium hydroxide in the step 1 in water, then adding a hydrofluoric acid solution and fluosilicic acid, and performing stirring at normal temperature for 10min; and 3, heating the solution prepared in the step 2 at a temperature of 60DEG C, adding an additive, a stabilizer and 10% of aluminum sulfate in a constant-temperature state, performing stirring for 30min, and adding 40% of aluminum sulfate. The concrete liquid accelerator provided by the invention is low in mixing amount, high in 1d strength, good in cement adaptability and low in production cost.
本发明公开了一种混凝土液体速凝剂，涉及液体速凝剂技术领域，所述具体的制备步骤包括：步骤一、按重量分别称取原料：氢氧化铝30%、氢氧化镁20%、硫酸铝50%、氢氟酸溶液35%、氟硅酸25%、添加剂1.8%、稳定剂0.8%和分散增强剂10.5%；步骤二、将步骤一中的氢氧化铝和氢氧化镁在水中进行混合，然后再加入氢氟酸溶液和氟硅酸，并在常温下进行搅拌，10min；步骤三、将步骤二制取的溶液进行加热，温度为60℃，在恒温状态下加入添加剂、稳定剂以及硫酸铝10%，搅拌30min后，加入硫酸铝40%。本发明提供的混凝土液体速凝剂，掺量低、1d强度高、水泥适应性好、生产成本低。
