This Self-Healing Concrete Can Repair Its Own Cracks

As solid and reliable as concrete structures may seem, they share one common enemy: tension. Over time, concrete will crack and deteriorate.

An invention by Delft University microbiologist Hendrik Jonkers offers an innovative approach to creating more stable concrete by adding limestone-producing bacteria to the mix.

This self-healing bioconcrete aims to provide a cheap and sustainable solution, markedly improving the lifespan of buildings, bridges and roads.
