Innovations in methods and ingredients have made possible lightweight bridges, color-changing buildings, and furniture created from this efficient material

Concrete is ubiquitous in the modern world, yet most people don't give it a passing thought. Why would they? It may be the most consumed substance on earth after water, but the stuff of pavements and parking garages is also a bit dull—or so most of us thought. In fact, innovations in the science of concrete have enabled architects and designers to achieve remarkable feats that would have been impossible in earlier years—everything from ultra-thin bridges spanning hundreds of feet to furniture made from lightweight blends.

One of the big factors behind the resurgence of concrete is the environmental movement. Scientists and architects have rediscovered concrete's potential to save energy, since its thermal efficiency reduces the need for air conditioning and heating. But with this reawakening has come demand for more lightweight, durable, and aesthetic concrete by the designers who use it. ..SNIP..

Years ago I was impressed with concrete that could be poured under water.

Isn't that a Roman Era innovation? I would hope we've come farther than that!
