Concrete is used in almost all types of structures or construction projects. Although it is resistant, it is also a very fragile material and is prone to cracking under any type of stress, from weather effects to reactions to other substances such as road salt and water. Now, researchers at the Worcester Polytechnic Institute in Massachusetts have created a new version of concrete that captures carbon dioxide that is in the air and manages to self-repair small and large cracks.

Inspired by the human body, the team added an enzyme found in red blood cells to dry concrete dust. The process takes only 24 hours, so repair begins at the same time the crack is generated, has no added cost, and is almost immediate. In fact, scientists think that this new material could multiply by 4 the period in which a construction project has an optimal structure, and therefore we could be in front of a revolutionary material.
