Self-healing concrete eats CO2 to fill its own cracks in 24 hours

“We looked to nature to find what triggers the fastest CO2 transfer, and that’s the CA enzyme,” says study author Nima Rahbar. “Since enzymes in our bodies react amazingly quickly, they can be used as an efficient mechanism to repair and strengthen concrete structures.”
The team put the CA enzyme to use by adding it to concrete powder before the material is mixed and poured. When a small crack forms in the concrete, the enzyme interacts with CO2 in the air to produce calcium carbonate crystals, which mimic the characteristics of concrete and promptly fill in the crack.
