It's bendable too!

There's a new kind of concrete on the market. It's supposed to be 500 times stronger then the normal goop. Also, in the long run it's supposed to save money on bridges since it lasts longer. So let's start spending that savings on knocking down the existing bridges so we can rebuild with this stuff!
The new mix contains mostly the same ingredients as regular concrete minus the coarse gravel, explained engineering Professor Victor Li. It looks like regular concrete, but under intense strain it gives instead of breaking because fibers slide within the cement. The fibers behave somewhat like your body's ligaments, holding things together in a flexible manner.
