WPI researcher develops self-healing concrete

Researchers at Worcester Polytechnic Institute announced on Tuesday they have developed a form of concrete that will fix its own cracks.

Using an enzyme found in red blood cells, they posit the new product is four times more durable than traditional concrete, and published their work in the journal Applied Materials Today. According to the research, the enzyme used in the material automatically reacts with atmospheric carbon dioxide to create calcium carbonate crystals, which mimic concrete in structure and strength, and can fill cracks before larger problems develop. The process can reportedly heal millimeter-scale cracks within 24 hours.
