The days of dull, grey concrete could be about to end. Get ready for windows that never break with translucent concrete. A German design firm has created load-bearing concrete containing optical fibers, allowing light and color to pass through to the other side (the shadowy hand is what you can see through the concrete in direct light). The result is that you can live inside a sunlit dome and still be protected when the space invaders come and drop those dangerous light thingies on your head. A Hungarian architect has combined the world’s most popular building material with optical fiber from Schott to create a new type of concrete that transmits light.
A wall made of “LitraCon” allegedly has the strength of traditional concrete but thanks to an embedded array of glass fibers can display a view of the outside world, such as the silhouette of a tree, for example.
“Thousands of optical glass fibers form a matrix and run parallel to each other between the two main surfaces of every block,” explained its inventor Áron Losonczi. “Shadows on the lighter side will appear with sharp outlines on the darker one. Even the colours remain the same. This special effect creates the general impression that the thickness and weight of a concrete wall will disappear.”
The hope is that the new material will transform the interior appearance of concrete buildings by making them feel light and airy rather than dark and heavy.
