Preface
The art of rheological measurements for construction materials was until 50 years ago a totally unknown territory. Even today it is often hard to understand, unless you are an expert in the field. There are many people who buy the costly equipment for rheological measurements. However, they often find after some time that the test set up, numerous influencing factors and the proper interpretation of the results is not that easy to work out. As a consequence this expensive equipment ends up lying in the corners of the labs gathering dust.
This conference and workshop on the “Rheology of Building Materials” in Regensburg cannot solve all these problems. It, however, supplies a platform for excellent presentations of recent research work as well as demonstrations of useful equipment and exchange of ideas.
The proper workability of materials bound by mineral binders is essential for an economic production and for a perfect performance in hardened state. The papers in these proceedings show examples of enhanced testing and applications.
These proceedings address important rheological topics:
• Inline control of ready mix concrete
• Tests on concrete and mortar for different purposes (e.g. rheology of calcium-sulfoaluminate mortars, of alkali activated binders, of mortars for 3D-printing)
• The influence of fibres on injecting mortars
• Oscillatory measurements.
The papers on mineral materials are enhanced with a special contribution on the behaviour of granular frazil ice. Hopefully, the reader will enjoy these papers and get a lot of inspiration as well as some new ideas for her/his own work.
Personally, due to my retirement this summer, this conference is the last I chair. In the future I will join you as an ordinary delegate. I wish Markus Greim, Oliver Teubert, Helena Keller from Schleibinger Testing Systems and my still unknown successor as chair a lot of success for the future. I would like to also thank them all for their engagement in this Conference, which is indeed the 29th.
Furthermore, I would like to thank all the authors and conference delegates for their contributions. I hope to meet you next year at the 30th anniversary at the OTH Regensburg.
