Simple and environment-friendly overall super-hydrophobic concrete preparation method and product
The invention discloses a simple and environment-friendly integral super-hydrophobic concrete preparation method and a product, relates to the technical field of super-hydrophobic concrete, and aims to solve the problems that the super-hydrophobic concrete is complex in preparation process or contains fluorine and does not have excellent super-hydrophobicity inside. The preparation method comprises the following steps: fully and uniformly mixing 100 parts by weight of cement and 80-150 parts by weight of sand, and adding 40-45 parts by weight of water; in the mixing process, 6-8 parts by weight of super-hydrophobic modified silicon dioxide solid powder is uniformly added at the same time, so that the prepared concrete generates more compact needle-shaped products with different sizes so as to have the layering roughness required by the super-hydrophobic surface, and concrete slurry is obtained by fully and uniformly stirring; the obtained concrete slurry is poured, hardened and formed to obtain the super-hydrophobic concrete structure; the steps are simple and easy to operate and control, the materials are green and environmentally friendly, the cost is low, and the prepared concrete has super-hydrophobicity after being rubbed or broken and is excellent in anti-icing performance and corrosion resistance.
本发明公开了一种简易环保的整体超疏水混凝土制备方法及产品，涉及超疏水混凝土技术领域，为解决超疏水混凝土或制备工艺复杂、或含氟，且内部不具备优异超疏水性的问题；本发明包括将100重量份水泥和80‑150重量份砂充分混合均匀后，加入40‑45重量份的水；在一边拌合的过程中，一边将6‑8重量份超疏水改性二氧化硅固体粉末均匀加入，用于使制得的混凝土生成更多致密且不同尺寸的针状产物从而具有超疏水表面所需的分层粗糙度，充分搅拌均匀得到混凝土浆料；将得到的混凝土浆料浇筑、硬化成型后得到超疏水混凝土结构；本发明步骤简单易操作、易控制，材料绿色环保，成本较低，制得的混凝土摩后或破开均具备超疏水性，防冰、耐腐蚀性优异。
