Light Transmitting Concrete

LiTraCon (which stands for Light Transmitting Concrete) is a concrete block that transmits light through its light conducting embedded glass fibers. Light passes from one side of the block to the other without any significant loss, illuminating the darker side. Shadows are transmitted in precise shapes on the opposite surface. Currently in its testing phase, the blocks will be available on the market by the end of 2004. These precast concrete blocks can be produced in all sizes. In addition, the fibers can be chosen in widths from 2 micrometers up to 2-millimeters and added to any specification required. This will give a more diffuse light, a grid, different patterns or even a logo. Developed by Hungarian architect Aron Losonczi, the blocks will be produced by LiTraCon, a German company which will be exhibiting them in the National Building Museum in Washington D.C. from June 19, 2005. Exhibitions will also be held in Stockholm, Eindhoven, Budapest, Cologne, Berlin, London, Glasgow and Frankfurt/Main. There is presently a demonstration project in Stockholm of a paving use that is very interesting. At sunset, underground light sources start to shine up through the concrete making it easier to see. Among the other projected applications for the translucent concrete is for use in subway and rail stations as well as for speed bumps on roads. For more information go to: www.litracon.com
