Composite material for dissolving concrete admixture precipitate, dissolving method and application
The invention provides a composite material for dissolving a concrete admixture precipitate, a dissolving method and application, and the method comprises the following steps: forming a solid-liquid mixture from the concrete admixture precipitate, sodium hydroxide, urea, copper hydroxide and water, and stirring the solid-liquid mixture until the concrete admixture precipitate is completely dissolved to prepare a precipitate dissolving solution; when the precipitate dissolving solution is compounded into a concrete admixture for use, the effects of water retention and thickening can be achieved. Compared with the prior art, the method has the advantages that the operation is simple and easy, the problem that the precipitation of the concrete admixture is difficult to treat can be solved, the dissolving solution can be used for compounding the admixture, and the compounding cost of the concrete admixture is reduced.
本发明提供了一种溶解混凝土外加剂沉淀的复合材料、溶解方法和应用，本发明将混凝土外加剂的沉淀与氢氧化钠、尿素、氢氧化铜和水形成固液混合物，将该固液混合物搅拌直至混凝土外加剂沉淀完全溶解制备得到沉淀溶解液；将该沉淀溶解液复配到混凝土外加剂中使用，可以起到保水及增稠的作用。与现有技术相比，本发明操作简单，易于操作，即能解决混凝土外加剂沉淀难以处理的问题，又能将溶解液用于外加剂复配中，降低混凝土外加剂复配成本。
