In this study, an environmentally friendly superhydrophobic surface for concrete (S-concrete) with excellent mechanical robustness and anti-corrosion performances was put forward. By introducing geopolymer material, a novel inorganic gelling material act as binders to enhance the stability of the S-concrete, the suspension based on stearic acid (STA) modified by micro diatomaceous earth (DE) and nano alumina (Al₂O₃) were intensely attached to the substrate. The structure morphologies, chemical compositions, surface wetting behavior of this S-concrete were systematically investigated by SEM, XRD, FT-IR and wettability measurements. The results showed that the S-concrete coating was successfully constructed by achieving a desirable static contact angle of 159.1° and a small slide angle 4.5°. The S-concrete features Cassie-Baxter phase contacts, liquids repellency, anti-fouling and self-cleaning properties. The S-concrete exhibited excellent resistance to chloride corrosion, which was reduced by about 2 orders of magnitude compared to ordinary concrete. What is more, this S-concrete coating showed remarkable robustness against sandpaper abrasion and tape-peeling, while retaining its superhydrophobicity even suffering 200 abrasion cycles and 60 tape-peeling. The improved durable mechanical robustness and interfacial bonding force can be attributed to the cross-linked three-dimensional hierarchical structures formed by the combination of geopolymer material and embedded DE/Al₂O₃@STA micro-nanoparticles.
