Self-healing concrete can automatically repair its own cracks, extending the life of structures and reducing maintenance.
It addresses the costly problem of concrete cracking that allows water and chemicals to corrode reinforcement.
The most common approach embeds dormant bacteria and calcium lactate in the concrete. When cracks form and water enters, the bacteria activate and produce limestone (calcium carbonate) that seals the crack.
Other methods use microcapsules of healing agents or special chemical admixtures that react with water to form crack-filling crystals.
