A New Methodology for the Assessment of the EoS Data of Concrete

The experimental determination of the equation of state is a complex and expensive task. This paper presents a new methodology for the theoretical determination of the equation of state for concrete. Mesomechnical simulations are conducted and compared to three sets of experimental data. It was also investigated whether the methodology used for the meso-scale modeling is applicable to a homogenized description of concrete. Based on more than 400 numerical simulations, it is shown that the EoS parameters which are determined on a purely theoretical basis agree well with both the experimental and the numerical results on a meso-level. Hence, the provided theoretical methodology enables modelers to assess the EoS parameters of concrete for most applications in a simple spreadsheet analysis.
