Composition for preparing low-alkali accelerator and preparation method of low-alkali accelerator
The invention provides a composition for preparing a low-alkali accelerator and a preparation method of the low-alkali accelerator. The composition for preparing the low-alkali accelerator comprises a sodium metaaluminate solution, aluminum sulfate, magnesium salt, fluorine-containing inorganic acid, phosphoric acid, organic alcohol amine, a stabilizer and water. The low-alkali accelerator prepared by the invention can achieve a better rapid setting effect under the condition of low mixing amount, including faster initial setting time and final setting time, higher compressive strength and stability and the like.
本发明提供了一种用于制备低碱速凝剂的组合物及低碱速凝剂的制备方法。本发明的用于制备低碱速凝剂的组合物及包括偏铝酸钠溶液、硫酸铝、镁盐、含氟无机酸、磷酸、有机醇胺、稳定剂和水。本发明制备得到的低碱速凝剂能够在低掺量的情况下达到较好的速凝效果，包括更快的初凝时间、终凝时间以及更高的抗压强度和稳定性等。
