Performance of Autogenous and Autonomous Self-Healing Concrete
Alireza Bahrami, Ramtin Shirkhodaee, Ali Jamshidi · MDPI AG · 2026
This study analyzes autogenous and autonomous self-healing concrete methods, highlighting their effectiveness, costs, and environmental impacts.
Plain English summary
Why this matters
Key findings
- Autogenous self-healing is effective for small cracks (<200 μm) and is cost-efficient.
- Autonomous self-healing can seal larger cracks (up to 1240 μm) but has higher production costs.
- Bacterial concentration and nutrient type significantly influence mechanical properties.
- Both methods reduce corrosion risk and extend service life.
- Autogenous self-healing is more feasible for large-scale applications due to lower costs.
What's new
The study provides a comprehensive analysis comparing autogenous and autonomous self-healing methods, including their environmental impacts and economic aspects.
Limitations
The abstract does not provide specific experimental results or detailed comparisons of performance metrics between the two methods.
Commercial context
The abstract does not indicate the commercial availability of the technologies discussed.
