Fluorine-free chlorine-free alkali-free liquid accelerator as well as preparation and application thereof
The invention relates to the field of building materials, in particular to a fluorine-free chlorine-free alkali-free liquid accelerator and preparation and application thereof, and the fluorine-free chlorine-free alkali-free liquid accelerator comprises the following components in percentage by mass: 55%-60% of aluminum sulfate, 5.5%-6.5% of diethanol amine, 2.0%-4.0% of magnesium oxide, 2.0%-4.0% of nano silicon dioxide, 2.0%-4.0% of polyacrylamide, 3.0%-5.0% of oxalic acid, 0.5%-1.5% of glycerol and the balance of water, and the sum of the components is 100%. Compared with the prior art, the invention has the advantages of improving the cohesiveness of slurry, reducing the rebound rate of concrete, enhancing the strength of a cement-based material, shortening the setting time and the like.
本发明涉及建筑材料领域，涉及一种无氟无氯无碱的液体速凝剂及其制备与应用，按各组分的质量百分比，包括：硫酸铝55％～60％，二乙醇胺5.5％～6.5％，氧化镁2.0％～4.0％，纳米二氧化硅2.0％～4.0％，聚丙烯酰胺2.0％～4.0％，草酸3.0％～5.0％，甘油0.5％～1.5％，水为余量，各组分之和为100％。与现有技术相比，本发明具有可以改善浆体粘聚性、降低混凝土回弹率、提升水泥基材料的强度、缩短凝结时间等优点。
