In 1992, a small group of committed scientists and practitioners, at that time under the leadership of Prof. J. Teubert, came together to exchange thoughts on the topic “The rheology of mineral building materials”. Interest has grown continually since that time and today the meeting is a fixed feature for many in the field of building material technology. The participants at this year’s event came from 16 countries. A total of 120 experts on building material technology had accepted the invitation given by Prof. Wolfgang Kusterle, OTH Technical University Regensburg, and Dipl.-Eng. Markus Greim, Schleibinger Geräte GmbH.
