Evaluation of the oxidation process of steel fibers in the presence of a potato dextrose and calcium chloride solution for the self-healing of cementitious matrices

Description
The objective of the research was to experimentally examine the corrosion of steel fibers in two media: a solution containing potato dextrose and calcium chloride (S1) (nutrient of the biological agent Oomicetum Pythium aphanidermatum that facilitates the self-healing of cementitious matrices), and water (S2). The corrosion process was accelerated by the Cebelcor method for 15 days, with immersion/emersion cycles of 5 and 19 hours, respectively. The results revealed that the corrosion of the fibers in solution S1 was 10.64% higher than that in S2. Regarding cross-sectional loss, the corroded fibers in S2 showed linear behavior, unlike those in S1, which exhibited pitting corrosion that varied along their longitudinal section. Therefore, it is recommended that future investigations evaluate this behavior using the galvanostatic method. Additionally, future research should evaluate the mechanical response of steel fiber-reinforced cementitious matrices incorporating self-healing mechanisms through the biological agent and its corresponding nutrient.
