Developing a Self-Healing Concrete Using Microencapsulated Bacteria
Quick fact
By embedding microencapsulated bacteria that produce limestone when activated by water, self-healing concrete can seal cracks up to 0.8 mm wide, potentially doubling the service life of structures.
Why this is interesting
Concrete is the most used building material on Earth, but it's prone to cracking. What if concrete could repair its own cracks, just like skin heals a cut?
