Concrete is one of the wide used building materials in both marine engineering and architecture field. The first step of concrete structure deterioration is that corrosive medium invades into concrete. In this paper, a non-toxic fabricating method of superhydrophobic concrete with anti-corrosion and stable mechanical properties was proposed. Copper mesh and stearic acid were used to obtain the hierarchical micro-nano structure and low surface energy. The results indicate that the water contact angle and water slide angle of fabricated superhydrophobic concrete reached 159° and 5°, respectively. In addition, even after 60 s of mechanical polishing, the water contact angle was still greater than 150°. Moreover, compared with ordinary concrete, the anti-corrosion of fabricated superhydrophobic concrete was greatly improved. The fabricated environment-friendly superhydrophobic concrete with anti-corrosion and stable mechanical properties has important potential application value in the marine engineering.

具有抗腐蚀和稳定机械性能的海洋环境用超疏水混凝土的制备

混凝土是海洋工程和建筑领域中广泛使用的建筑材料之一。混凝土结构劣化的第一步是腐蚀性介质侵入混凝土。提出了一种防腐,力学性能稳定的超疏水混凝土无毒制备方法。用铜网和硬脂酸获得分层的微纳米结构和低表面能。结果表明,所制备的超疏水混凝土的水接触角和滑水角分别达到159°和5°。另外,即使在机械抛光60秒之后,水接触角仍大于150°。而且,与普通混凝土相比,预制的超疏水混凝土的防腐性能大大提高。
