Anti-freezing accelerator, preparation method thereof and sprayed concrete
The invention provides an anti-freezing accelerator, a preparation method thereof and sprayed concrete. The anti-freezing accelerator is prepared from the following raw materials in percentage by weight: 50-60% of aluminum sulfate, 2-5% of inorganic salt, 0.5-1.0% of a stable component, 1-3% of an anti-freezing component, 2-5% of an organic complexing component, 0.005-0.02% of an inorganic nano component and the balance of water. All the preparation raw materials of the anti-freezing accelerator have a synergistic effect, the anti-freezing accelerator is stable in state in a low-temperature environment, when the anti-freezing accelerator is mixed and added into concrete, the setting time of the concrete can be shortened, the early-stage and later-stage strength of the concrete can be improved, and when the anti-freezing accelerator is used for spraying the concrete, the rebound rate can be reduced.
本发明提供了一种抗冻型速凝剂及其制备方法和喷射混凝土，该抗冻型速凝剂的制备原料中有效成分按重量百分比计包括：50‑60%硫酸铝、2‑5%无机盐、0.5‑1.0%稳定组分、1‑3%防冻组分、2‑5%有机络合组分、0.005‑0.02%无机纳米组分，其余为水。该抗冻型速凝剂的各个制备原料协同作用，低温环境下抗冻型速凝剂状态稳定，当拌合加入混凝土时，可以使混凝土的凝结时间缩短，提高混凝土的早期和后期强度，用于喷射混凝土，可降低回弹率。
