**9. Conclusions**

This paper provided the guidelines to predict the temperature field in a concrete structure based on limited input data. The proposed solution, taking into account the thermal and chemical aspect of the hardening concrete, allowed us to simulate successfully the temperature changes in cast-in-place concrete of box bridge girder. The main results of the experimental and numerical studies could be summarized as follows:


model parameters: κ/*n*0, *n* and *A*0/κ. In order to increase the quality of determined parameters, it was recommended to perform both experiments, for two mentioned curing conditions.
