Litracon is a new revolutionary construction material

LiTraCon™ offers the phenomena of light transmitting concrete in form of a widely applicable new building material. LiTraCon™ is a combination 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. Probably 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.

Thousands of optical glass fibres form a matrix and run parallel to each other between the two main surfaces of every block. The proportion of the fibres is pretty small (4%) compared to the total volume. What is more they mingle in the concrete because of their insignificant size, they become a structural component as a kind of modest aggregate. The surface of the blocks therefore still reminds of homogeneous concrete.
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.

LiTraCon™ was invented by Hungarian architect Áron LOSONCZI in 2001. The international jury of German Design Zentrum Nordrhein Westfalen gave the'red dot: best of the best' award for highest design quality to LiTraCon™. LiTraCon™ is also nominated for the Design Award of the Fed. Republic of Germany 2006.
