Fluoride-free alkali-free accelerator and preparation method thereof
The invention relates to the technical field of accelerators and production thereof, in particular to a fluoride-free alkali-free accelerator and a preparation method thereof, and the fluoride-free alkali-free accelerator comprises the following raw materials: aluminum sulfate octadecahydrate, isopropanolamine, acidic silica sol, acetic acid and softened water. The fluoride-free alkali-free accelerator is free of fluoride ions and alkali metal ions, alkali aggregate reaction caused by the alkali metal ions can be avoided, concrete has the advantage of durability, fluorine-containing componentsare not contained in the components, damage of the fluoride ions to people and the environment in the construction process is avoided, water quality pollution of the fluoride ions to the environmentis also avoided, and on the above premise, the setting time is shorter, and mortar strength is higher.
本发明涉及速凝剂及其生产技术领域，是一种无氟无碱速凝剂及其制备方法，前者原料包括十八水合硫酸铝、异丙醇胺、酸性硅溶胶、醋酸和软化水。本发明所述无氟无碱速凝剂既无氟离子，也无无碱金属离子，不仅能避免碱金属离子造成的碱集料反应，使混凝土具有耐久性的优点，又在组分中无含氟成分，避免氟离子在施工过程对人和环境的侵害，也避免了氟离子对环境的水质污染，在此前提下，具有更短的凝结时间，更高的砂浆强度。
