Self-healing concrete is a type of concrete that can automatically repair its own cracks and damage. This innovative material contains special additives, such as bacteria or polymer capsules, that activate when water enters a crack. The additives then produce substances that fill the gap, restoring the concrete's strength and durability. This technology aims to extend the lifespan of concrete structures, reducing maintenance costs and improving safety. Self-healing concrete is particularly useful in infrastructure projects, such as bridges and roads, where cracks can lead to significant issues over time.
