To investigate the durability of magnesium (Mg) oxychloride-coated reinforced concrete (MOCRC) and the deviation from the natural corrosion process of the electrified accelerated corrosion test in reinforced concrete, the authors used the electrified accelerated corrosion test with saline soil as an electrolyte. A quality test, a dynamic elastic modulus test, a crack-width test, an electrochemical performance test and a microscopic test were conducted regularly. The test results show that the relative quality evaluation parameter ω 1, the relative dynamic elastic modulus evaluation parameter ω 2 and the relative corrosion evaluation parameter ω 3, which characterise the degradation of MOCRC, all gradually decrease as the electrification time increases. Failure standards were reached at 24, 21 and 21 days, respectively. Analysis of morphology, corrosion current density and corrosion rate shows that the morphology of the coated steel bar under accelerated corrosion is consistent with natural corrosion. Using saline soil as the electrolyte of the accelerated corrosion system can simulate steel bar corrosion in a natural environment better than a traditional salt solution can.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
