Alkali-free and chlorine-free liquid setting accelerator, preparation method and use method of alkali-free and chlorine-free liquid setting accelerator
The invention discloses an alkali-free and chlorine-free liquid accelerator as well as a preparation method and a use method thereof, and belongs to the technical field of building materials. According to the invention, polyaluminum sulfate is used as a base material, and a part of functional additives are added, including 45-50 wt.% of polyaluminum sulfate, 0.5-1 wt.% of a composite water reducer, 5-10 wt.% of magnesium sulfate, 5-10 wt.% of alcohol amine, 2-5 wt.% of calcium fluoride, 2-4 wt.% of a stabilizer, and the balance of water. The preparation method comprises the following steps: preparing the composite water reducer, dissolving and mixing, stirring and feeding, and uniformly dispersing. The composite water-reducing accelerator is specially added into the accelerator, so that the mechanical property of the accelerator is effectively improved, the 1d compressive strength is improved by 42.86%, the 28d compressive strength is improved by 7.7%, and the alkali-free and chlorine-free requirements are met. And the cement and the admixture have good compatibility, and can be widely applied to various application fields such as tunnels, slope protection, mines, 3d printing and the like.
本发明公开了一种无碱无氯液体速凝剂、制备方法及其使用方法，属于建筑材料技术领域。本发明以聚合硫酸铝为基料，添加部分功能助剂，包括聚合硫酸铝45‑50wt.％，复合减水剂0.5‑1wt.％，硫酸镁5‑10wt.％，醇胺5‑10wt.％，氟化钙2‑5wt.％，稳定剂2‑4wt.％，余量为水。其制备过程包括复合减水剂的制备、溶解混合、搅拌加料、均匀分散。本发明速凝剂特别添加复合减水速凝剂，有效提高了速凝剂力学性能，使1d抗压强度提高42.86％，28d抗压强度提高7.7％，达到无碱无氯要求。且水泥、掺合料相容性好，可广泛用于隧道、护坡、矿井、3d打印等多种使用领域。
