This Self-Healing Concrete Can Fill Its Own Cracks With CO2

Concrete is known to crack when it shrinks, and that often happens after a faulty mixture dries and hardens. Water from the faulty mixture evaporates, which could even pull the slabs apart, leaving structures in need of repair. However, a newfound self-healing concrete mixture treats cracks independently and repairs itself in a specified time.
