When
and Where
Organized by the Macsinet
Working Group “ Concrete as a Multiphase Porous Material”
at the Technical University
of Lódz (Poland) on 8-9 May 2002
Introduction:
Recent research on modelling
of concrete as a multiphase porous material has reached maturity with several
international collaborative efforts. They have been mainly prompted by
problems related to performance of High Performance- and Ultra High Performance-
concrete structures. During their life, micro-structural, physical and
chemical transformations take place, influencing the material’s thermal,
hygral and mechanical properties, especially in fresh concrete or concrete
subject to high temperature. It is essential, that concrete structures
are designed to withstand above ambient service and accidental conditions
without losing their function and load-bearing capacity. It is, therefore,
fundamental that the influence of physical and chemical phenomena is understood
at the micro, meso- and macro- levels.
First, main achievements of
modern concrete technology will be summarised on the wide background of
historical and future perspectives of concrete structures. Then, recent
advances in theory of concrete as a multiphase porous medium will be presented,
including the most difficult aspects, like modelling of concrete at early
ages or behaviour of concrete at high temperature. Practical application
of the theory for analysis of High Performance Concrete structures during
fire will be shown and discussed, together with its experimental verification
and application for real concrete structures. Then, theoretical and technological
aspects of practical application of self-compacting concrete will be discussed.
Finally, some recent experimental results concerning practical application
of Carbon-Fibre Reinforced Plastics for repairing of concrete structures
will be presented. A wide panel discussion of recognised concrete researchers
with representatives of civil engineering practice will conclude the workshop.
It will give an overview of practical problems which should be addressed
in further research from one side, and deliver some new ideas for practitioners
about new technologies available nowadays and in future, from the other
side.
