It was at the end of a Gordon Conference in Italy, in the late nineties, that Professor Wittmann kindly offered me a lift to Pisa. During that trip we discussed the idea of organizing an international workshop on concrete modelling. Modelling of concrete at different scales and with input from different disciplines. Obviously our trip was too short to fix a date already. Probably we both intuitively felt that, in spite of our excitement about such an event, every-day business would not leave us with time to organize it. But the idea was there and, fortunately, this time postponement did not lead to cancellation. A couple of years later I discussed the idea with colleagues from Switzerland, USA, Canada, Japan and Belgium. Their positive reactions made us deciding to set the preparations for a concrete modelling conference in motion.
The original plan was to organize the first CONMOD conference in 2006. However, that would have created a big overlap with a RILEM symposium in Quebec, where one of the themes was just on Concrete Modelling, the theme we were aiming at. We decided to postpone our Concrete Modelling conference with two years until 2008. Meanwhile we ‘baptized' the Quebec symposium the first CONMOD conference in a series of conferences on this particular topic. Since much progress is expected in the field of modelling in the coming decade, the intention is now to organize a series of CONMOD conferences with an interval of two years. This will enable PhD students working on this topic to attend two CONMOD conferences during their study. This is considered a good condition for making contacts with colleagues from all over the world and for intensifying these contacts if appropriate.
CONMOD conferences are supposed to be a platform for researchers active in modelling of concrete at different length scales and coming from different scientific disciplines. During the conferences the background of models will be discussed, for what purpose models are developed, the modelling concepts and computation techniques that are adopted, as well as the validation of models.
The fact that almost hundred papers were submitted to CONMOD’08 from more than twenty countries illustrates the relevance of the topic and the interest of researchers to share their ideas and results with colleagues. We do hope that sharing and discussing ideas will generate further momentum in modelling activities, break open unexpected directions in research and will, in the end, lead to improvements and innovations in materials and structural design.
CONMOD’08 is a RILEM event and has been organized jointly by the University of Genth / Magnel Laboratory and Delft University of Technology / Microlab. The organizers would like to thank all the sponsors of CONMOD’08 and the respected delegates from all over the world to make this conference a success. Finally I would like to express my appreciation for Professor Wittmann’s presence as one of our keynote speakers. Klaas van Breugel
