Cambridge University is researching the potential of “self-healing” concrete, using microencapsulation technologies developed by Dolomite Microfluidics.
Microcapsules containing “healing” agents – such as epoxy or polyurethane – are added to the material to allow self-repair of small cracks which develop due to fatigue.
Cambridge’s researchers plan to add the microcapsules to the concrete prior to use, which are ruptured as cracks appear, releasing their payload and stabilising the material.
