The invention discloses an alkali-free accelerator and a preparation method thereof, and relates to the technical field of accelerator preparation. The concrete admixture is prepared from the following preparation agents: aluminum sulfate, sodium citrate, a polycarboxylate superplasticizer, ammonia water, a thickener and a stabilizer. The preparation agent is prepared from 40%-60% of aluminum sulfate, 5%-10% of sodium citrate, 5%-10% of a polycarboxylate superplasticizer, 5%-10% of ammonia water with the concentration of 15%-25%, 1%-3% of a stabilizer and 1%-2% of a thickener. The ratio of thepreparation agent to the water ranges from 1: 1.1 to 1: 1.3. The accelerator is generated from aluminum sulfate, sodium citrate and ammonia water, does not contain metal ions, and has no corrosivityor pungent smell; by adding the stabilizer, the stability is high, and the adaptability is high; and the manufacturing process is simple, convenient and fast.
本发明公开了一种无碱速凝剂及制备方法，涉及速凝剂制备技术领域。本发明包括如下制备剂：硫酸铝、柠檬酸钠、聚羧酸减水剂、氨水、增稠剂以及稳定剂；制备剂的比例如下：硫酸铝40％‑60％、柠檬酸钠5％‑10％、聚羧酸减水剂5％‑10％、浓度为15％‑25％的氨水5％‑10％、稳定剂1％‑3％以及增稠剂1％‑2％；制备剂与水的比例范围为1:1.1‑1:1.3。本发明通过通过硫酸铝、柠檬酸钠以及氨水生成速凝剂，不含金属离子，无腐蚀性和刺激性气味；通过添加稳定剂，稳定性高、适应性强；且制作程序简单，方便快捷。
