January 26, 2006 Thanks to a lot of unimaginative work over the last half century, concrete has a bad name, yet at the same time, some of the world’s most beautiful and innovative works of contemporary architecture derive their character from the material. Interestingly, though concrete might seem a low tech material, it is evolving. We’ve recently written about bendable concrete and now there’s Light Transmitting Concrete (known as LiTraCon), which is created by mixing concrete and glass fibres optical strands to create a solid yet translucent block suitable for floors, pavements and load-bearing walls. The inventor of LiTraCon, Hungarian architect Aron Losonczi, gave a public lecture at the United States National Building Museum earlier this week to present his revolutionary product that brings translucence to a traditionally opaque material. The lecture complements a current exhibition at the Museum entitled Liquid Stone: New Architecture in Concrete, which features a five-foot tall LiTraCon wall.
