Resumo Inglês:

This paper is devoted to simulate the behavior of reinforced concrete in saline solution through the accelerated corrosion test. During this test, this method was evaluating the behavior of the steel bars that reinforce concrete for corrosion, according to the NACE 0775 standard. After the corrosion test, the steel bars were cleaned and dried according to the ASTM A380 standard and evaluated according to the NACE RP 0775, NACE SP0308, and NACE SP0187 standards. From the results obtained, the steel bars concrete showed high corrosion rates with structural impairment of the metal armor according to the NACE standards.
