Following the International Workshop on autogenous shrinkage of concrete "Autoshrink' 98" organised by the Japan Concrete Institute in Hiroshima (Japan, 1998) and the International Research Seminars on self-desiccation and its importance in concrete technology in Lund (Sweden, 1997 and 1999), the International RILEM Workshop on Shrinkage of Concrete "Shrinkage 2000" have been hold in Paris, in October 2000. This workshop have dealt with different aspects relative to autogenous and drying shrinkage, including the effect of mixture composition, influence of moisture, size-effects, ....

Therefore, why is so much effort presently devoted to the study of a phenomenon known for such a long time? Why organise another international workshop on shrinkage?

What do we know exactly about shrinkage in the year 2000?

Do we know how to measure shrinkage precisely? Are we measuring the right things?

These are some of the questions that have been raised and discussed during this workshop, with the leading objectives to:
- analyse and discuss autogenous and drying shrinkage mechanisms, in order to explain the peculiar behaviour of these new concretes,
- propose new and relevant testing methods, in order to assess the different components of the deformations of concrete.
- promote tools for a better prediction of the deformations of concrete structures,
- prevent negative effects of shrinkage (early-age cracking, ...) and prepare ad-hoc recommendations.
