By Birgit Baustädter - Concrete is a widely used building material. It is durable, robust and locally available. And it has a reputation for not being very sustainable. Experts from TU Graz explain what concrete is and how it can become (more) sustainable. "It's best if you come to my lecture - concrete is such a broad field," says a laughing Markus Krüger , head of the Institute of Technology and Testing of Construction Materials at Graz University of Technology (TU Graz).

"Concrete is first and foremost a mass building material that has excellent properties and allows us to construct things as we have conceived them and as would not be possible with any other building material." Rock, cement and water.
