8. Self-Healing Concrete
• Self-healing concrete is an innovative and advanced
construction material designed to repair cracks that
naturally occur in concrete over time.
• It employs embedded materials or mechanisms within the
concrete mix to autonomously seal and heal cracks, thus
extending the service life of structures and reducing the
need for frequent maintenance.

9. SELF HEALING
PROCESS

10. Mechanisms of Self-Healing
Bacterial Healing
In this approach, bacteria or microbial agents are mixed into the concrete. When
cracks form and moisture enters, these bacteria produce calcite (a mineral form
of calcium carbonate) through a process called microbial-induced calcite
precipitation (MICP). This calcite fills the cracks, effectively sealing them.
Capsule-Based Healing
In this method, microcapsules containing healing agents (such as epoxy or
polyurethane) are incorporated into the concrete. When cracks appear, the
capsules rupture, releasing the healing agents, which then react and fill the
cracks.
Mineral Precipitation
Some forms of self-healing concrete incorporate reactive materials that, when
exposed to water entering through cracks, form mineral deposits that seal the
gaps.

11. Advantages
Increased Durability
Self-healing concrete improves the overall durability of structures by preventing water
ingress and protecting reinforcing materials from corrosion.
Reduced Maintenance
The self-repairing capability reduces the need for frequent maintenance and repair work,
leading to lower maintenance costs over the lifespan of a structure.
Extended Service Life
By healing cracks in real time, self-healing concrete contributes to a longer service life for
concrete structures, reducing the need for premature replacements.
Enhanced Sustainability
The reduction in maintenance and repair work results in fewer material replacements,
which aligns with sustainable construction practices and reduces environmental impact.
Mitigation of Structural Degradation
Self-healing mechanisms prevent cracks from propagating and compromising the
structural integrity of concrete elements.

12. Applications
Infrastructure
Self-healing concrete is particularly useful for critical infrastructure
like bridges, tunnels, and highways, where continuous exposure to
environmental factors can lead to cracking and degradation.
Buildings
In residential and commercial buildings, self-healing concrete can
contribute to improved longevity and reduced maintenance costs.
Industrial Facilities
Facilities with harsh conditions, such as chemical plants, wastewater
treatment plants, and power plants, can benefit from the durability of

Incorporating self-healing mechanisms can add complexity to the
production process and require careful mixing and handling.
Long-Term Performance
The long-term performance and reliability of self-healing mechanisms
need to be thoroughly tested and validated over extended periods.
