Concrete air entraining agent, preparation method and application
The invention relates to a concrete air entraining agent, a preparation method and application, and belongs to the technical field of concrete admixtures. The nano-porous silicon dioxide foaming agent is prepared from the following raw materials in parts by weight: 372-740 parts of nano-porous silicon dioxide dispersion liquid, 4-10 parts of a thickening component, 20-40 parts of an air entraining component and 1-10 parts of a defoaming component. The concrete air entraining agent provided by the invention has good air entraining and foam stabilizing effects in concrete, and can effectively improve the bubble stability of newly mixed concrete in a plateau low-pressure environment. The preparation method of the air entraining agent is simple, convenient, short in time consumption, environment-friendly and easy to meet large-scale industrial production.
本发明涉及一种混凝土引气剂、制备方法及应用，属于混凝土外加剂技术领域。由以下原料制成：纳米多孔二氧化硅分散液372‑740份、增稠组分4‑10份、引气组分20‑40份、消泡组分1‑10份。本发明混凝土引气剂在混凝土中具有良好的引气及稳泡的作用，能够有效提升新拌合混凝土在高原低气压环境下的气泡稳定性。本发明的引气剂制备方法简便，耗时短，环境友好，易于满足大批量工业化生产。
