Alkali-free, fluorine-free and chlorine-free liquid setting accelerator as well as preparation method and application thereof
The invention discloses an alkali-free, fluoride-free and chlorine-free liquid setting accelerator and a preparation method and application thereof, and the alkali-free, fluoride-free and chlorine-free liquid setting accelerator comprises the following components in percentage by mass: 45-65% of aluminum sulfate, 1-8% of magnesium sulfate, 3-10% of alkylol amine and 20-50% of water. The alcohol amine is diethanol amine and triethanolamine, and the mass ratio of the diethanol amine to the triethanolamine is (2-8): 1. The alkali-free, fluorine-free and chlorine-free liquid setting accelerator has the characteristics of short initial setting time and final setting time, high early strength, high later strength retention rate, good stability, greenness and harmlessness; more importantly, the setting accelerator can meet the standard requirement of concrete on the setting time under the condition that the mixing amount is 3%-7%; and the setting accelerator has good adaptability, and can be suitable for cement of various brands and manufacturers.
本发明公开了一种无碱无氟无氯液体速凝剂及其制备方法和应用，按质量百分数计，包括以下组分：硫酸铝45％‑65％，硫酸镁1％‑8％，醇胺3％‑10％，水20％‑50％；所述醇胺为二乙醇胺和三乙醇胺，其中二乙醇胺和三乙醇胺的质量比为2‑8：1。本发明的无碱无氟无氯液体速凝剂具有初凝、终凝时间较短，且早期强度高、后期强度保留率大、稳定性好、绿色无害的特点；更为重要地是，该速凝剂在3％‑7％的掺量下即可满足混凝土对凝结时间的标准要求；并且该速凝剂的适应性好，可以适用各种不同牌号、厂家的水泥。
