The Workshop IRWRMC18 and the Round Robin Test RRT "Comparison of Concrete Rheometers:
International Tests at the Artois University were organized on 28 to 30 May and 31
May 2018 on the rheology and tribology of concretes, respectively. These two events are part
of the issues developed by RILEM and in particular within the framework of the actions carried
out by the RILEM - TC MRP-266 Committee: Measuring Rheological Properties of Cement-
based Materials chaired by Dr Mohammed SONEBI from Queen’s University Belfast
(UK).
This is not the first time that international researchers and laboratories have been investigating
the rheology of cement-based materials since two other RRTs were organized:
- The first RRT at LCPC in Nantes (France) in 23-27 October 2001,
- The second RRT organized by NIST in Cleveland (USA) in 19-23 May 2003.
After 15 years, there was no RRT organized on this topic. However, during this period, the
progress has been considerable, as much by the widening of the range of the new type concretes,
the progress made by the new devices (new and up rheometers) and finally the way to
analysis of the results.
The workshop was organized in 4 sessions on one day. The importance of the number of
communications received showed the interest raised by this theme on rheology which is essential
from the point of view of industrial applications. The technical and economic implications
are considerable.
The workshop brought together 78 participants including 54 from the academic world and 24
industrialists who benefited from 22 communications. It is nice to note that researchers from
around the world (Germany, Belgium, Brazil, Chile, China, UK, India, Ireland, Italy, USA,
etc.) have contributed to this important workshop. The participants were able to discuss recent
and latest scientific knowledge on the rheology of concrete.
Special thanks go to Professor K. H. Khayat from the University of Missouri, whose many
works are published in this area of rheology of concrete.
It should be noted the participation of several manufacturers such as Botte Foundations, Roquette
SA, Eqiom, Soletanche Bachy, Holcim-Lafarge, Saint Gobain, Léon Grosse,
Schleibinger, etc.
Some papers have been selected to be published in the journal of the French Rheology Group
Rheology.
We would like also thank and acknowledge many sponsors of these two events: the National
Federation of Public Works, EQIOM, Boot Foundations, Structure & Réhabilitation, the
French Group of Rheology, Artois Comm, the University of Artois and LGCgE Lille Nord de
France.
