Werner Sobek in the Deutschlandfunk Podcast
A contribution by Deutschlandfunk that is well worth listening to is devoted to the most important building material of recent decades – concrete. Long regarded as the perfect solution for a wide variety of building tasks, the image of the “building material of the century” has become clearly tarnished in recent years, not least for reasons of sustainability.
The Deutschlandfunk programme is therefore entitled “A building material seeks a successor – concrete as a climate polluter”. Among the experts interviewed for the programme is Prof. Werner Sobek. He reports on his research into gradient concrete, with which weight savings of 50 percent and more can be achieved. The podcast can be found here.
