This Self-Healing Concrete Has Trapped Bacteria To Repair Cracks In Structures

This bio-concrete has self-healing capacities and can repair cracks in concrete structures by itself.

Researched by Dr. Henk Jonkers at the Delft University of Technology in The Netherlands, it’s now possible to embed calcite-precipitating bacteria in the concrete mixture that heals itself as if it were alive.



Repairing cracks in concrete structures is time-consuming and costly but this breakthrough using bacterial mineral precipitation gives hope to save billions in repair costs by extending the life-span of structures.

The concrete mixture has food and bacteria added at the early stage. This enables the bio-concrete to be infused with bacteria that awakens when it has contact with water and it starts to produce limestones.

It has the capability to close even big holes with the calcium carbonate within three weeks of getting triggered. The bacteria can lay dormant for around 200 years within the bio-concrete.
