Hungarian architect Áron Losonczi delivered a presentation at
the National Building Museum about his invention LiTraCon, or light-transmitting
concrete, a revolutionary product that brings translucence to the traditionally
opaque material.
Mr. Losonczi discussed the evolution and use of this unique
material in various projects, among them the Freedom Tower in New York City. The
lecture complemented the exhibition, sponsored by Lafarge North America, titled
"Liquid Stone: New Architecture in Concrete," which also featured a
five-foot tall LiTraCon wall. A reception hosted by the Hungarian Embassy
preceded the program.
