Structural pathology attempts to assess the actual state of a structure to predict its behavior and lifespan, considering several factors, including weathering. Chemical exposure to the chloride ion is known as the worst threat to the composition of reinforced concrete structures, as its presence exponentially accelerates the corrosive phenomenon. The objective of this research is to correlate the characteristic properties in cores extracted from reinforced concrete structures throughout the country with the chloride content, as well as with the level of exposure to environmental chloride, determined in each of the chloride capturing stations, by using the wet candle method. The results obtained indicate that all stations installed nationwide presented an exposure category S1 (according to ISO 9223). Similarly, a marked inversely proportional relationship was also observed between the distance to the sea of the structures with the chloride content in the samples and with the level of environmental exposure. Furthermore, it was found that the age of the structure can be used as an indicator in the performance of reinforced concrete structures. For subsequent studies, it is recommended to evaluate the use of technological methods and tools that facilitate collection and chemical analysis of samples, including a prolonged record of relative humidity, and increasing the study period to at least one year, to analyze chloride levels as a function of time and weather conditions.
