Alkali-free, chlorine-free and fluorine-free liquid accelerator, application and concrete
The invention provides an alkali-free chlorine-free fluorine-free liquid accelerator, which is prepared from the following components in percentage by mass: 46 percent to 53 percent of aluminum sulfate, 5.5 percent to 6.5 percent of diethanol amine, 5.0 percent to 7.0 percent of oxalic acid, 2.0 percent to 3.0 percent of magnesium oxide, 0.5 percent to 1.5 percent of glycerol and the balance of water. 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 significantly improve the initial setting time, the final setting time and the 1d compressive strength of the concrete. Meanwhile, the invention also provides concrete containing the alkali-free, chlorine-free and fluorine-free liquid accelerator.
本发明提供了一种无碱无氯无氟的液体速凝剂，以质量百分数计，包括：46％‑53％的硫酸铝、5.5％‑6.5％的二乙醇胺、5.0％‑7.0％的草酸、2.0％‑3.0％的氧化镁、0.5％‑1.5％的甘油以及余量的水。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、终凝时间和1d抗压强度。同时，本发明还提供了一种含有上述无碱无氯无氟的液体速凝剂的混凝土。
