The invention discloses an alkali-free concrete accelerator and a processing method thereof. The alkali-free concrete accelerator comprises the following raw materials in parts by weight: 30-65 partsof aluminum sulfate, 2-8 parts of an organic amine, 1-3% of a stabilizer, 1-5 parts of a suspending agent, 20-35 parts of water, 2-5 parts of bentonite and 4-6% of magnesium fluosilicate. In the present invention, the caulking agent for building decoration of prefabricated parts is simple in preparation method, low in cost, is liquid after preparation, can be uniformly mixed with concrete conveniently, contains no alkali or chlorine or pungent smell, is high in safety, is harmless to human body, is excellent in cohesiveness; adding of a stabilizing agent can prolong the storage time, preventdeterioration; magnesium fluosilicate and aluminum sulfate are adopted for cooperative using, so that the resilience value is low, later strength retention rate is high, and impermeability grade is high; adding of the alkali-free concrete accelerator in sprayed concrete is capable of achieving a preferable working environment and considerable market value.
本发明公开了一种无碱混凝土速凝剂及其加工方法，包括以下重量组份的原料：硫酸铝30～65份，有机胺2～8份，稳定剂1‑3％，悬浮剂1～5份，水20～35份，膨润土2～5份，氟硅酸镁4～6％。本发明中，该用于预制构件建筑装修用的嵌缝剂，制备方法简单，成本较低，制备后为液体状态，便于与混凝土混合均匀，且为无碱、无氯、无刺激性气味，安全性高，对人体没有伤害，并且粘结性好、通过稳定剂的添加，提高其存储时间，防止其变质，氟硅酸镁、硫酸铝配合使用，使得回弹量低、后期强度保存率高、抗渗级别高，在喷射混凝土中添加本发明的无碱速凝剂，可带来较好的工作环境，市场价值可观。
