Fluoride-free liquid accelerator as well as preparation method and application thereof
The invention discloses a fluoride-free liquid accelerator which comprises the following raw materials: aluminum sulfate, alkylol amine, organic alcohol, organic acid, a viscosity regulator, a modified nano material and water, and the modified nano material is a nano material treated and modified by a dispersing agent. The accelerator disclosed by the invention can meet the standard requirement of concrete on the setting time under the doping amount of less than or equal to 6%, is fluoride-free, alkali-free and chlorine-free, and has the advantages of short setting time, high early strength, high later strength retention rate, greenness and harmlessness.
本发明公开了一种无氟液体速凝剂，其包括以下组分的原料：硫酸铝、醇胺、有机醇、有机酸、粘度调节剂、改性纳米材料和水，其中，所述改性纳米材料为用分散剂处理改性的纳米材料。本发明的速凝剂在≤6％的掺量下即可满足混凝土对凝结时间的标准要求，且该速凝剂无氟无碱无氯，具有凝结时间短，早期强度高、后期强度保留率大、绿色无害的优点。
