Abstract (EN): This work provides an analysis of results obtained in a set of carbonation tests performed in 38 concrete structures buildings located in the city of Asuncion, Paraguay. This analysis has shown that structures present high values of carbonation depth, identifying the cover thickness as the most important parameter in terms of durability. Therefore, the aim of this paper is to give an outlook for optimal inspections in the context of maintenance strategies regarding carbonation-induced degradation of concrete structures in Paraguay. The optimisation problem is formulated through a quantification of cost components over the lifespan of structures, where the optimal inspection plan is considered when a minimum total expected cost of maintenance is accomplished.
