Original Abstract

The service life assessment is not on the safe side when neglecting the synergy of mechanical and environmental load. In order to make the service life design realistic it is necessary to take into consideration the both of them acting simultaneously. The paper deals with an advanced modelling of concrete carbonation and chloride ingress into concrete. For both, carbonation and chloride ingress, widely agreed models are extended by correction factors to reflect the coupling effects. Comparisons of numerical results to real structure behaviour are shown on realistic examples of cooling tower and reinforced concrete beams.
