Developed in 2001 by a Hungarian architect, translucent concrete has taken its time hitting the press. However, it deserves all the accolades it’s now garnering, and more. The optical fibres that run parallel to one another throughout the material allow light and color to pass through walls of concrete up to 20 meters thick! The fibers’ thicknesses can also range from 2μm (micrometers) to 2mm, depending on how much light the consumer wants to allow through. It may be some time before translucent concrete is perfected (modifications to speed the production process have already begun), but once it hits the popular market, I predict it’ll be in a big way.
