Concrete has a massive carbon footprint, so technologies that boost its performance and enable it to last longer could have profound benefits for the environment. This has led to the development of self-healing concrete that can repair its own cracks, and scientists have now demonstrated an exciting new form of this that makes use of an enzyme found in human blood. ...
This field of research has turned up all kinds of interesting potential solutions over the years. We've seen versions that pack their own
sodium silicate healing agents, ones that feature bacteria that
produce special glue to knit together these cracks, and others that
fill up the gaps with fungus. While promising, scientists at the Worcester Polytechnic Institute have conjured up what they believe is a cheaper and even more efficient solution. ...
