Loss of durability has always been a matter of concern in concrete structures exposed to severe weather conditions. Exposure to ice or snow, as an example, can cause freezing-induced damage, resulting in expansion and cracking. Superhydrophobic surfaces, which are typically icephobic (ice-repellent) can prevent water penetration in concrete, protecting the structure from damage. With this study, using different additives, we aim to develop a new concrete mix with hydrophobic properties, suitable for 3D printing.
