Superhydrophobic surface is one of the important strategies for the application of water and ice resistance. In this study, we focused on the nano structure of hydration product itself of cement and superhydrophobic surface was created on hardened cement pastes (HCP) without any additive. The surface microstructures and surface chemical composition of ordinary HCP (O-HCP) and superhydrophobic HCP (S-HCP) both were characterized by SEM and FTIR respectively. The results of water absorption and anti-icing tests showed that the prepared S-HCP had lower water permeability, ice-adhesion strength and ice accumulation than O-HCP. Meanwhile, the surface of S-HCP remained superhydrophobic property after a series of mechanical performance tests and weather resistance tests, which indicated that the SCM has great application potential.

超疏水表面是应用抗水和抗冰的重要策略之一。在这项研究中，我们专注于水泥水化产物本身的纳米结构，并且在不添加任何添加剂的硬化水泥浆（HCP）上创建了超疏水表面。普通HCP（O-HCP）和超疏水性HCP（S-HCP）的表面微观结构和表面化学成分分别用SEM和FTIR表征。吸水和防冰测试结果表明，所制备的S-HCP比O-HCP具有较低的透水性，冰粘附强度和冰积聚。同时，经过一系列的机械性能测试和耐候性测试，S-HCP的表面仍保持了超疏水性，这表明SCM具有很大的应用潜力。
