HERNANDEZ, Y. et al. Reinforcement corrosion rate and crack width relationship in concrete beams exposed to simulated marine environment. Rev. ALCONPAT [online]. 2016, vol.6, n.3, pp.271-282. ISSN 2007-6835.  https://doi.org/10.21041/ra.v6i3.152.

This investigation presents an empirical correlation between the rebar corrosion rate and the corrosioninduced crack width propagation rate produced on beam's concrete cover, with or without load application to these beams. Reinforced concrete beams were evaluated, exposed to a natural corrosion process by spraying with 3.5 %w/w NaCl solution, to accelerate the rebar corrosion process, was performed with electrochemical tests. The beams corrosion-cracking evaluation was performed once every month, to determine the relation between crack width and the rebar corrosion loss. The results showed a direct relation between crack width propagation and rebar corrosion rate, showing wider cracks in the loaded beams.
