SELF-HEALING CONCRETE SMART TECHNOLOGY

<p>Concrete is one of the most widely used construction materials, yet it is prone to cracking, which<br>compromises structural integrity and leads to costly repairs. Self-healing concrete is an innovative smart<br>technology designed to enhance the durability and longevity of concrete structures by autonomously<br>repairing cracks. This technology integrates biological, chemical, or mechanical healing mechanisms to<br>restore structural integrity without human intervention.<br>The most promising self-healing techniques include bacterial self-healing, where bacteria embedded in the<br>concrete produce limestone to seal cracks, and capsule-based systems that release healing agents upon<br>crack formation. Additionally, shape-memory materials and vascular networks mimic biological healing by<br>supplying repair materials to damaged areas.<br>Self-healing concrete significantly reduces maintenance costs, improves sustainability, and extends the<br>lifespan of infrastructure. It has applications in roads, bridges, buildings, and underground structures,<br>making it a revolutionary advancement in modern construction technology. This project explores the<br>mechanisms, advantages, and potential challenges of self-healing concrete while highlighting its role in<br>smart infrastructure development.</p>
