Abstract: Two basically different types of concrete models were developed during the recent years:
First, models which simulate the formation of the microstructure by calculating the individual phase reactions, e. g. CEMHyd3D. These models are able to predict the properties of a large variety of concretes. Second, models based on empirical equations which were found by experiments, e.g. DuCOM. These models can model large specimens by using finite element models (FEM). Both types have the ability to produce reasonable predictions of the progression of hydration and other concrete properties. The paper will present the results of simulations which were obtained by coupling three independent modules. One module simulates the hydration, one program computes the strength and one solves the FE equations.
