LiTraCon™ was invented by Hungarian architect Áron Losonczi in 2001. Inventor and patent holder founded his own company LiTraCon Bt in spring 2004. The head office and the workshop is located to Hungarian town Csongrád, 160km far from capital Budapest.
LiTraCon™ offers the phenomena of light transmitting concrete in form of a widely applicable new building material. LiTraCon™ is a combiantion of optical fibres and fine concrete and can be produced as prefabricated building blocks and panels. Because of their small size the fibres blend into concrete becoming a component of the material like small pieces of aggregate. In this manner, the result is not only having two materials - glass in concrete - mixed, but a third, new material which is homogeneous in its inner structure and on its main surfaces as well. The glass fibres lead light by points between the two sides. Because of their parallel position the light-information on the brighter side of such a wall appears unchanged on the darker side. Propably the most interesting form of this phenomenon is the sharp display of shadows on the opposing side of the wall. Moreover, the colour of the light remains the same too.
In theory, a wall structure built out of light-transmitting concrete can be a couple of meters thick as the fibres work almost without any loss in light up till 20 meters. Load-bearing structures can also be built of these blocks, since glass fibres do not have a negative effect on the well-known high compressive strength value of concrete. The blocks can be produced in various sizes and with embedded heat-isolation too.
