Bendable Concrete

Traditional concrete will only take so much pressure before it breaks. A team led by Victor Li of the University of Michigan in Ann Arbor has developed a new type of concrete that bends under such pressure and 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. With this new material, bridges can be constructed without expansion joints. Buildings made of it will also be safer during earthquakes. Link -via Unique Daily
