Anti-freezing anti-erosion hydrophobic concrete and preparation method thereof
The invention relates to anti-freezing and anti-erosion hydrophobic concrete and a preparation method thereof.The hydrophobic concrete is prepared from, by weight, 10-18 parts of cement, 3-8 parts of admixture, 70-80 parts of aggregate, 5-8 parts of water, 0.2-1 part of water repellent and 0.01-0.6 part of water reducing agent, the water repellent is precipitated silica modified by hexadecyl silane coupling agent, and the water reducing agent is silicon dioxide modified by hexadecyl silane coupling agent. And the particle size of the water repellent is 2-30 [mu] m. The specific water repellent is used in cooperation with other components of the concrete, the internal and external waterproof performance of the concrete can be effectively enhanced, the influence of concrete surface abrasion on the waterproof effect is small, and the concrete has the durability such as excellent freezing resistance, permeability resistance and erosion resistance while obtaining the strength equivalent to that of conventional concrete.
本发明涉及一种抗冻抗侵蚀憎水混凝土及其制备方法，按重量份计，所述憎水混凝土的原料包括水泥10‑18份、掺合料3‑8份、骨料70‑80份、水5‑8份、憎水剂0.2‑1份和减水剂0.01‑0.6份，其中，所述憎水剂为十六硅烷偶联剂改性的沉淀二氧化硅，且所述憎水剂的粒径为2～30μm。本发明中采用特定的憎水剂协同混凝土其他组成的使用，可有效增强混凝土的内外防水性能，混凝土表面磨损对防水效果的影响小，且混凝土在获得常规混凝土相当强度的同时，还具有优异抗冻性、抗渗透性及抗侵蚀性等耐久性能。
