The paper presents a critical analysis of tools designed for describing the concrete corrosion process within the frame of the thermodynamics of a multicomponent continuum. The mixtures theory of reacting components, through averaging the variables of state, balance equations, and stoichiometric relationships of the sources, formulates an initial-boundary value problem characterising the progress of concrete degradation.
On this basis, a simplified phenemenological model can be built with an emphasis on the mechanical aspect of material deterioration. A scalar parameter was used to describe material damage within the framework of continuum damage mechanics. This parameter can be used to assess the change of structural memeber bearing capacity.
