Regenerative Cementitious Skins

<p dir="ltr">This research explores a sustainable method to enhance concrete durability by applying thin, self-healing engineered cementitious composite (ECC) skins to exposed surfaces. These regenerative skins autonomously heal damage, significantly reducing the need for repairs, extending service life, and minimising material use throughout the structure’s lifecycle. By using targeted applications of 5–20 mm thickness, the study demonstrates up to 100% crack healing with up to 60% less material than traditional methods, while maintaining comparable performance. This cost-effective approach is suitable for both new and existing structures and offers rapid deployment for large-scale maintenance, especially in hard to access areas like bridges and tunnels.</p>
