Science News has an interesting feature about the future of concrete. For example, Ductal is five times as strong as regular concrete, but it also bends a bit under heavy loads and shows “warning” cracks instead of failing in an instant.

Scientists and architects have been pushing the limits of this humdrum material to give it new features and creative functions. “Liquid Stone,” a current exhibit at the National Building Museum in Washington, D.C., portrays the future of concrete. The show includes ultrahigh-performance concrete that bends like metal and another type of concrete that forms translucent blocks.



In pursuit of environmentally friendly construction materials, engineers are also giving concrete a hard look. Already among the most essential construction materials, concrete now seems poised to take on new roles.
