Self-healing Concrete

Despite our best efforts, concrete will crack, requiring costly maintenance.

I found an article on self-healing concrete containing bacteria.  https://www.epo.org/learning-events/european-inventor/finalists/2015/jonkers.html

“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.”

Below is a video about this unique concrete material.
