The invention discloses a concrete protective material and a preparation and construction method thereof, the concrete protective material is composed of 50-90% by mass of a component A and 10-50% by mass of a component B. The component A is prepared from 30-65% by weight of organosilicon, 2-5% by weight of nano-silica and the balance of an organic solvent; and the component B is prepared from 20-50% by weight of organic alkali and the balance of water. According to the invention, nano-particles with a reinforcing effect can be formed in capillary channels on the surface layer of concrete, and the surface layer of the concrete can achieve a super-hydrophobic technical effect. 本发明公开了一种混凝土防护材料及其制备和施工方法，其由50-90％的A组分和10-50％的B组分按照质量百分数组成，其中：所述A组分由有机硅30-65％、纳米二氧化硅2-5％和余量的有机溶剂按照重量百分数制备而成；所述B组分由有机碱20-50％和余量的水按照重量百分数制备而成。本发明不仅能够在混凝土表层毛细孔道内形成具有增强效果的纳米颗粒，而且还能使混凝土表层达到超疏水的技术效果。
