LiTraCon (light transmitting concrete) is a combination of optical fibers and fine concrete. Thousands of fibers run side by side transmitting light between the two main surfaces in each block. Because of their small size, the fibers blend into the concrete, becoming a component of the material like small pieces of ballast. As a result, the two materials are not just mixed – glass in concrete – but a third, new material is produced which is homogenous in its inner structure and on its main surface as well.


LiTraCon finds applications mainly in architecture and interior design. LiTraCon blocks are used like bricks or passable paving illuminated from beneath. A wall structure created by LiTraCon can be a couple of meters thick, as the fibers work almost without any loss in light up to 20 meters. Moreover, the blocks are load-bearing and provide the same effect with both natural and artificial light. Glass fibers lead light by points between the wall surfaces. Shadows on the lighter side will appear with sharp outlines on the darker one.


LiTraCon is manufactured by LiTraCon GmbH (Tanya 832, 6640 Csongrád, Hungary) and was first introduced in 2005.
