Dutch microbiologist develops self-healing bio-concrete
Concrete buildings and other structures that are able to close and self-heal stress-induced cracks are no longer utopia but can soon become reality, thanks to an invention by the Dutch microbiologist Hendrik Marius Jonkers. His vision consisted of increasing the tensile strength and enhancing the environmental soundness of concrete with the aid of nature, reducing in this way both the costs of concrete production and maintenance, and of containing the resulting CO2 emission. Towards this objective, Jonkers developed a bio-concrete with bacteria that can survive up to 200 years in a concrete...
