Resumo

The contact of reinforced concrete with the saline mist is sometimes unavoidable, but we must follow the norms in order to minimize and / or even eliminate the probability of proliferation of manifestations in order to extend the useful life of the Parts.From this came the curiosity to verify why of the pathological manifestations and with the results in hand make an analogy with the norms to verify the compliments thereof.In our study, tests were carried out to verify the corrosion of reinforcement, both with the use of Phenolphthalein, for Carbonation Depth, and Silver Nitrate, in order to visualize the presence of Free Chlorides.From the tests it was identified that the agent causing the corrosion was the Chlorides.It was also seen that the parts were not produced according to the standard, since it used a coating of 2,0cm, instead of 4,5mm, normalized, which caused that the harmful agents arrive with a shorter time in order to reduce the life of the part and require replacement.
