Alkali-free liquid accelerator containing fluorosilicate, application of alkali-free liquid accelerator and concrete
The invention provides a fluosilicate-containing alkali-free liquid accelerator which comprises the following components in percentage by mass: 46%-50% of aluminum sulfate, 39%-41% of an aluminum fluoride solution, 6%-7% of magnesium fluosilicate, 2.0%-3.5% of diethanol amine, 1%-2% of magnesium sulfate and 0.5%-1.0% of a suspension stabilizer. The accelerator is prepared by mixing the raw material components step by step under the conditions of constant-temperature water bath and conventional stirring. The accelerator is suitable for sprayed concrete, and can obviously improve the initial setting time and the final setting time of the concrete. Meanwhile, the invention also provides concrete containing the alkali-free liquid accelerator containing the fluosilicate.
本发明提供了一种含氟硅酸盐的无碱液体速凝剂，以质量百分数计，包括：46％‑50％的硫酸铝、39％‑41％的氟化铝溶液、6％‑7％的氟硅酸镁、2.0％‑3.5％的二乙醇胺、1％‑2％的硫酸镁、0.5％‑1.0％的悬浮稳定剂。该速凝剂通过在恒温水浴和常规搅拌条件下的分步骤混合各原料组分的方法制备得到。该速凝剂适用于喷射混凝土中，可以显著改善混凝土的初凝、终凝时间。同时，本发明还提供了一种含有上述含氟硅酸盐的无碱液体速凝剂的混凝土。
