Translucent concrete


Yesterday I was having a look at some new material on the web and I found the translucent concrete.

Talking with my studio-mates I quickly realized that I was the only one who did ignore its existence…Is it that famous?? Where was I when it was invented?

So I’m going to write a quick post for those one like me that weren’t aware of this big invention.

Anyway, don’t be too excited because it’s really expensive…

Basically the translucent concrete, or light transmitting concrete is a combination of optical fibres and fine concrete.

The most famous seems to be Litraco.

From their website: It can be produced as prefabricated building blocks and panels. Due to the small size of the fibres, they blend into concrete becoming a component of the material like small pieces of aggregate. In this manner, the result is not only two materials – glass in concrete – mixed, but a third, new material, which is homogeneous in its inner structure and on its main surfaces as well. The glass fibres lead light by points between the two sides of the blocks. Because of their parallel position, the light-information on the brighter side of such a wall appears unchanged on the darker side. The most interesting form of this phenomenon is probably the sharp display of shadows on the opposing side of the wall. Moreover, the colour of the light also remains the same


It has been invented by a Hungarian architect in 2001 (and it took me 8 years to discover its existence) and it is protected by a Swedish patent.

 The standard block size is 600 x 300 mm

The price: the cheapest is the 25mm thick panel which costs 845 Euros, the more expensive is the 200mm thick panel which costs 3880 Euros. It means that, for example, if I want to use it for an facadeof 6 by 3 meters…the price is 388,000 Euros.

Then we have other brands like translucentconcrete by Andreas Bittis, produced in Germany by Florack, but there are no prices on the website.

Anyway, the use of translucent concrete looks to be applied only to small design objects, I couldn’t find any application in buildings. If you are aware of any project using the translucent concrete…here we are.
