N2 - This report deals with numerical modelling of early age concrete.
The hydration process giving the strength and stiffness
development after casting is discussed. Several factors influence
the progress of hydration such as the temperature level and the
moisture activity. The factors are coupled and a material model is
proposed which includes some of the couplings. It is shown how
more factors may be incorporated. The model is illustrated through
analysis of measured creep response both at a varying load history
and at a varying temperature history.
