LiTraCon is a trademark for a translucent concrete construction material. The name is abbreviated to "concrete that transmits light". The technical data sheet of the manufacturer says that the material is made of 96% concrete and 4% by weight of optical fibers, was developed in 2001 by the Hungarian architect Áron Losonczi who works with scientists of the Technical University of Budapest.
LiTraCon is manufactured by the inventor's company, LiTraCon Bt, which was founded in spring 2004. The main office and workshop are close to the city of Csongrád. Since 2006 all LiTraCon products have been produced by LiTraCon Bt. Concrete comes in prefabricated blocks of different sizes.
The most notable installation to date is the Europa Gate, a 4 m high sculpture made of LiTraCon blocks, erected in 2004 in fulfillment of Hungary's entry into the European Union. The product won the German "Red Dot Design Award 2005" for the "highest design qualities". Although costly, Litracon attracts architects because it is stronger than glass and translucent, unlike concrete. It has been considered as a possible coating for the One World Trade Center in New York.
