i couldn’t resist posting one more fascinating use of concrete. litracon, or light transmitting concrete, is a phenomenal new product. as the name suggests, this concrete is actually capable of allowing light, and conversely shadow, pass through it. the holy grail of concrete has always been transparency and litracon comes pretty close. as strong and as capable as its standard concrete predecessor, litracon owes its abilities to the addition of fiber optics. the fiber optics run parallel to each other and perpendicular to the concrete block or wall; in this way light and shadow on one side of the wall are visible on the other.
no word on other ingredients so it’s tough to make a judgment on its sustainability but its ingenuity is certainly off the charts. backlighting litracon with artificial light produces a brilliant glowing quality. meanwhile, daylighting behind a person or another object produces an almost ethereal ghostly silhouette. i can’t wait until this stuff goes mainstream. head on over to their website for some more great images, samples, example projects, and a small video of litracon in action.
