Abstract
Corrosion of steel in reinforced concrete structures can lead to cracking of concrete due to the volumetric expansion of the oxide respect to the steel. To study such a cracking, accelerated corrosion tests were conducted using concrete prisms with a smooth steel tube as reinforcement. After corrosion, the pattern of cracking was studied in cross-sections of the prisms and a quantitative analysis was carried out in order to compare the pattern between samples. Complementary, the tests were numerically simulated using a model that reproduces the volumetric expansion of the oxide and that works with finite elements with an embedded adaptable crack to reproduce cracking of concrete following the standard cohesive model. The numerical and experimental results coincided, although sections with a tube resulted to be more sensitive to the parameters of oxide than sections with a solid bar, which may constitute a means to investigate the oxide generated.
