Today everything is about concrete. In liquid form you can drive it through the city and a little while later, when it has hardened sufficiently, cars and trains drive over the new concrete bridge.
However achieving the right quality requires great care in the production and preparation of concrete. To help us make the right mixture of concrete we have Herr Andorfer of Güteverband Transportbeton with us as a guest. Together we will examine the consistency of our concrete, and he will tell us a lot about this raw material.
