self-healing concrete...!!

First they have bendable concrete, then these engineers introduced light transmitting concrete to the world, now we have a self-healing concrete that is bendable.
A team led by Victor Li of the University of Michigan in Ann Arbor has developed a new type of concrete that bends under pressure and the best part is, it can repair itself! The self-healing concrete develops many hairline fractures when bent, distributing the pressure over its area. The tiny cracks will seal themselves with calcium carbonate when exposed to rainwater and carbon dioxide.
