Abstract

In the current manuscript, laboratory tests were performed to accelerate the corrosion process of steel specimens. It used the Tamori's methodology, also known as the electrolytic corrosion. The tests were performed in twenty circular reinforced mortar specimens and divided into four main groups. The cement used was the Brazilian Portland CP-V ARI, and the rebar was CA-50 with a 6.3 mm nominal diameter. After applying a constant electric current for a specific time in the steel rebars of the reinforced mortar specimens, it was possible to identify stains and fissures in the specimens’ faces. The specimens were fractured, the rebars were removed, and later subjected to a thermochemical bath. Finally, the rebars had different percentages of corrosion loss when compared with theoretical values from the literature.
