Alkali-free chlorine-free fluorine-free environment-friendly liquid accelerator as well as preparation method and application thereof
The invention belongs to the field of building materials, and particularly relates to an alkali-free, chlorine-free and fluorine-free environment-friendly liquid accelerator as well as a preparation method and application of the alkali-free, chlorine-free and fluorine-free environment-friendly liquid accelerator. The accelerator comprises the following components in percentage by weight: 40%-48% of aluminum sulfate, 10%-15% of sodium metaaluminate, 5%-10% of magnesium sulfate, 2%-5% of organic acid, 5%-7% of a stabilizer, 0.2%-1% of a flocculant and the balance of water. The accelerator disclosed by the invention is simple in preparation method, free of alkali, chlorine and fluorine, capable of enabling the concrete to be rapidly coagulated by adding the accelerator into the concrete, and has the effects of early strength and corrosion resistance, no harm or pungent smell is generated in the preparation process, no harm is caused to the production of the accelerator and the bodies of constructors, and the accelerator is a novel green and environment-friendly accelerator. The accelerator is successfully applied to Dalian subway No.5 line engineering.
本发明产品属于建筑材料领域，特别是涉及一种无碱无氯无氟的环保型液体速凝剂、制备方法及其应用。该速凝剂按重量配比包括：硫酸铝40％‑48％，偏铝酸钠10％‑15％，硫酸镁5％‑10％，有机酸2％‑5％，稳定剂5％‑7％，絮凝剂0.2％‑1％，其余为水。本发明的速凝剂，制作方法简单，无碱、无氯、无氟，添加该速凝剂至混凝土中，能够使混凝土迅速凝结，具有早强、抗腐蚀性的效果，制作过程无危害或刺激性气味生成，对生产速凝剂以及施工人员的身体没有危害，是一种新型绿色环保型速凝剂。该速凝剂在大连地铁5号线工程中得到了成功的应用。
