Concrete anti-carbonization agent as well as preparation method and application thereof
The invention discloses a concrete anti-carbonization agent and a preparation method and application thereof, and belongs to the technical field of concrete.The anti-carbonization agent is prepared from, by weight, 210-260 parts of nano-silica solution, 52-65 parts of alkylol amine, 23-32 parts of polypropylene hollow fiber, 1.5-2.7 parts of penetrant, 3-5 parts of organic modified montmorillonite and 130-150 parts of deionized water. A preparation method of the concrete anti-carbonization agent comprises the following steps: mixing the polypropylene hollow fibers with deionized water while stirring, then sequentially dropwise adding alcohol amine and a nano silicon dioxide solution, and after continuous reaction, sequentially adding the penetrating agent and the organic modified montmorillonite to obtain the concrete anti-carbonization agent. The invention also discloses an application of the anti-carbonization agent in inhibition of concrete carbonization, and provides concrete at the same time. The concrete anti-carbonization agent provided by the invention has the advantages of long duration, high anti-carbonization efficiency, low cost and convenience in application.
本发明公开了一种混凝土防碳化剂及其制备方法与应用，属于混凝土技术领域，该防碳化剂包括以下重量份数的原料：纳米二氧化硅溶液210‑260份、醇胺52‑65份、聚丙烯中空纤维23‑32份、渗透剂1.5‑2.7份、有机改性蒙脱土3‑5份和去离子水130‑150份。其制备方法包括以下步骤：边搅拌边将聚丙烯中空纤维与去离子水混合，然后依次滴加醇胺和纳米二氧化硅溶液，持续反应后，依次加入渗透剂和有机改性蒙脱土，得到所述混凝土防碳化剂。本发明还公开了上述防碳化剂在抑制混凝土碳化中的应用，同时提供了一种混凝土。本发明提供的混凝土防碳化剂，具有持续时间长、抗碳化效率高、成本低和应用方便的优势。
