Concrete accelerator
The invention discloses a concrete accelerator which comprises the following components in percentage by mass: 60-72% of chitosan-based polyaluminum ferric sulfate, 25-35% of modified magnesium lithium silicate and 3-5% of an organic early strength agent. The concrete accelerator provided by the invention not only can promote the activation of cement, shorten the setting time, reduce the mixing amount and increase the later strength, but also can improve the impermeability of concrete.
本发明公开了一种混凝土速凝剂，以质量分数计包括：壳聚糖基聚合硫酸铝铁60‑72%、改性硅酸镁锂25‑35%和有机早强剂3‑5%。本发明提供的混凝土速凝剂，不仅可以促进水泥的活化，缩短凝结时间，减少掺量，增加后期强度，还能提高混凝土的抗渗性。
