Recent advances in self-healing concrete : stimulated and autonomous healing

The formation of small cracks (< 300 µm in width) in concrete is almost unavoidable. These cracks may not cause a direct risk of structural collapse, but do accelerate concrete degradation, and may hence reduce the structure’s service life. It is clear that cracks above a certain critical width form a direct path along which aggressive agents can penetrate into the concrete towards the steel reinforcement. Especially penetration of carbon dioxide or chloride will increase the risk for initiation and propagation of steel reinforcement corrosion. When cracks would be healed upon occurrence, a significant extension in service life can be achieved and environmental burdens related to maintenance and repair can be avoided to a large extent.
