The report deals with mathematical models for concrete at early
age. In the hardening process chemical reactions take place and
the concrete skeleton is created. The processes changes the
moisture content and produces heat. The associated temperature
rise gives expansion of the material which may lead to cracks in
the later cooling phase. The matrial model has intrigate couplings
between the involved mechanics, and in the thesis special
emphasize is put on the creep behaviour. The mathematical models
are based on experimental analysis and numerical implementation of
the models in a finite element concept.
