SELF-HEALING CONCRETE: MATERIALS AND MECHANISMS

Cracks in concrete structures represent a persistent issue that compromises their reliability and durability. Traditional repair methods are expensive and often impractical, especially for large-scale infrastructure projects. Self-healing concrete offers an innovative solution through autogenous and autonomous healing approaches. According to research, autogenous mechanisms are effective for cracks up to 150 µm, while autonomous methods can seal cracks up to 500 µm, improving mechanical properties, water tightness, and resistance to external influences. This paper analyzes materials, and mechanisms of self-healing concrete, highlighting its potential for sustainable and resilient infrastructure in the future.
