Non-uniform corrosion states of rebar in concrete under chloride environment

摘要

This study proposes and verifies a numerical framework that can efficiently quantify non-uniform corrosion penetration depth along the perimeter of the rebar in concrete exposed to chloride environment. Moreover, this framework considers the effects of rebar size and location on the process of chloride ingress into concrete and evaluates the non-uniform corrosion states that correspond to two scenarios of corrosion penetration depth: corrosion of segment of the rebar and uneven corrosion along the rebar perimeter. Qualitative, comparisons of the evaluated non-uniform corrosion states with the variety of available laboratory and field data show good agreement. (C) 2015 Elsevier Ltd. All rights reserved.
