With the monitoring of the degree of realkalinization, through pH and half-cell potential measurements at 7, 14, 21 and 28 days, pH recovery is observed in all cases, obtaining characteristic half-cell potential values in each current application, which confirms the polarization of the steel modifying the thermodynamic condition of the concrete-steel interface and causing chemical changes in the concrete paste. With the NMX-C-553-ONNCCE-2018 standard the steel was polarized without reaching the overprotection region, avoiding the risk of producing hydrogen and brittleness in the steel.</p&gt;}, number={3}, journal={Revista ALCONPAT}, author={Paat Estrella, Paat Estrella and Miam Cuevas, Jose Alexandro and Maldonado Bandala, Erick Edgar and Perez Lopez, Tezozomoc and Nieves Mendoza, Demetrio}, year={2022}, month={Sep.}, pages={347 - 361} }
