Litracon: light-transmitting concrete
Litracon, invented by Hungarian architect Áron Losonczi, presents the phenomenon of light transmitting concrete in the form of a widely applicable new building material.
Litracon is a combination of optical fibers and fine concrete. It can be produced as prefabricated building blocks and panels. Due to the small size of the fibers, they blend into concrete becoming a component of the material like small pieces of aggregate.
The glass fibers lead light by points between the two sides of the blocks. The most interesting form of this phenomenon is probably the sharp display of shadows on the opposing side of the wall.
Interesting to see if these go mainstream. Where and how much?
