Deterioration of reinfroced concrete structures in a marine environment in brazil: a case study

摘要

Nowadays the corrosion of reinforcement is the most harmful damage that can occur in refinforced concrete structures. The case study is one analysis form utilized for to verify the damages evolution when the structure is exposed in environment. In a residential building located at saline environment in Brazil was made measures of carbonation depth, chloride ions and to apply an new assessment method for to establish quantitatives boundaries for structures degradation. The results showed that the carbonation depth was smaller than concrete cover, but the amount of chloride ions in structural elements was biggest than the threshold vlaue. The structure deterioration and immediate intervention on structure for to restore the serviceability levels. So, this work show make real the possibility of to verify the damages evolution in a structure, using simple inspection procedures with a numeric analysis.
