    Corrosion and Chloride Diffusivity of Reinforced Concrete Cracked under Sustained Flexure
    (Turkish Chamber Civil Engineers, 2020) Özyurt, Nilufer; Soylev, Tayfun Altug; Özturan, Turan; Pehlivan, Ahmet Onur; Nis, Anil
    This research discusses the chloride diffusivity of concrete as well as corrosion performance of rebars in cracked and uncracked states. Prismatic concrete specimens with two water-to-cement ratios, two concrete cover thicknesses with and without steel fibers were used. Three-point flexural loading was applied to form cracks and cracks were sustained by a bolt system. Half-cell potential and corrosion rate measurements were carried out following wetting drying cycles in chloride environment which were continued for 80 weeks. The positive effects of lower water-to-cement ratio and greater cover depth were found to be surpassed by existence of cracks in concrete.
