Concrete liquid accelerator
The invention belongs to the technical field of accelerators, and particularly relates to a concrete liquid accelerator. Aiming at problems in the prior art that the existing powdery accelerator has the disadvantages of low dissolving speed, difficult dispersion and the like, and can be only applied to dry spraying process construction; most of the powdery accelerators contain strong alkaline substances so that eyes and skin of construction workers are easily injured and concrete strength is easily reduced, a scheme is provided, wherein the concrete liquid accelerator comprises 35-45 parts ofaluminum sulfate, 3-9 parts of sodium fluoride, 6-12 parts of a defoaming agent, 7-10 parts of a stabilizer, 5-10 parts of glycerol, 10-15 parts of hydroxycarboxylic acid, 4-10 parts of a preservative, 5-12 parts of a thickener, 10-20 parts of a peculiar smell adsorbent and 35-55 parts of water. The concrete liquid accelerator is convenient to prepare, the dissolving speed is increased, the working efficiency is improved, workers and the environment are not damaged, the anti-corrosion performance of concrete is improved, and the strength of the concrete is enhanced.
本发明属于速凝剂技术领域，尤其是一种混凝土液体速凝剂，针对现有的粉状速凝剂存在溶解速度慢，不易分散等缺点，且仅能应用于干喷工艺施工，大部分粉状速凝剂含有强碱性物质，易对施工工人眼睛和皮肤造成伤害，且易降低混凝土强度的问题，现提出如下方案，其包括以下成分：硫酸铝35‑45份，氟化钠3‑9份，消泡剂6‑12份，稳定剂7‑10份，甘油5‑10份，羟基羧酸10‑15份，防腐剂4‑10份，黏稠剂5‑12份，异味吸附剂10‑20份，水35‑55份。本发明制备方便，提高了溶解速度，提高的工作效率，不会对工作人员和环境造成损害，提高混凝土的防腐性能，增强混凝土的强度。
