Chloride ions migration and induced reinforcement corrosion in concrete with cracks: A comparative study of current acceleration and natural marine exposure
The aim of this paper is to investigate the corrosion relationship between reinforced concrete exposed to natural marine environment and applied current acceleration. Chloride ions migration and reinforcement corrosion behaviour in different cracked concrete are studied by two testing methods: 700-day exposure in a marine tidal zone and applied current accelerated corrosion. The mechanism comparison of chloride ion diffusion between two techniques is discussed. The results show that cracks have more influence on reinforced concrete under electrochemical corrosion than that under natural exposure. The corrosion rates of natural and accelerated corrosion were quantitatively compared: the latter is two orders of magnitude faster than the former when the crack width is over 0.20 mm. The different composition and distribution of corrosion products between techniques are demonstrated. (C) 2020 Elsevier Ltd. All rights reserved.
