Interesting…they use some sort of bacteria, that can survive in concrete, and is activated if when water reaches it after a crack. It is, apparently, to protect the metal reinforcing that, if/when rusted/corroded enough, will defeat the structure.](“http://www.cnn.com/2015/05/14/tech/bioconcrete-delft-jonkers/index.html”)
