Due to the porous characteristics of cement-based materials, they are often corroded by salt solutions, which results in decreased durability, especially against damage under freeze-thaw cycles (FTCs).
Improving surface properties is an effective way to improve the durability of these materials.
In this study, a hydrophobic coating was applied to the surface of cement mortar by chemical modification of low surface energy materials.
Fourier transform infrared spectroscopy (FT-IR) showed that low surface energy substances are linked to hydration products through chemical bonds.
A water contact angle test indicates that the surface of cement mortar changed from hydrophilic (θ = 14°) to hydrophobic (θ = 140°) after chemical modification.
The cumulative water uptake of hydrophobic samples decreased by 90%.
Meanwhile, the wear resistance of the hydrophobic coatings was excellent.
Compared with the baseline sample, mass loss rate, flexural strength, and compressive strength of hydrophobic coating samples increased several-fold in the FTC test.
Microstructural changes of the mortar were characterized by scanning electron microscopy.
The results show that a hydrophobic coating can significantly improve the freeze-thaw resistance of cement-based materials.
The formation of a hydrophobic layer on the surface of cement-based materials can improve their durability.
The research results not only have applications in civil engineering but will also have great impact in the restoration of historic structures.
