Self-healing concrete is being trialled by a group of researchers from Bath, Cambridge and Cardiff universities in the UK.
The Materials for Life project is investigating three self-healing technologies that could eventually be individually or collectively incorporated into concrete as it is made.
It is claimed that self-healing concrete could significantly reduce the annual bill for repairing concrete buildings and structures.
The trial is investigating three technologies: shape-memory polymers, healing agents, and bacteria that produces calcium carbonate.
