Self-Healing Concrete?

Posted by in Concrete | November 06, 2012

Cracking is probably the most troublesome issue for concrete.  But cracking may less of an issue in the future.  A university in the Netherlands has developed a healing agent for concrete.  It is an agent with limestone producing bacteria and nutrients.  When added to the concrete mix it has been shown to result in the “healing” of cracks up to 0.5 mm.  The product is still be improved so that larger width cracks can be healed.  There is also the testing in real world applications.  So we are still a few years, maybe decades away.

Now if they could develop a bacteria that fills in pot holes, they could make a fortune in the Cleveland area.
