Concrete is vulnerable to the elements. But now, researchers have developed a concrete embedded with self-repairing ‘BioFibers’.Summary
KEY POINTS:
- Temperature fluctuations force cracks in concrete, which allows moisture to enter and eat away at it.
- The polymer fibres in the BioFibers act as physical reinforcements.
- When ‘woken’, the dormant bacteria begin a process that fills and patches up the crack.
