Abstract

Concrete structures built in marine environment are susceptible to attack by chemicals such as chloride which diffuses into concrete structures and attack the reinforcements embedded in reinforced structures and break down the reinforcement protective layer. This paper presents the use of Abaqus Finite Element Analysis software in Analyzing the processes involved in concrete structure degradation from chloride diffusion to concrete cracking. Mass diffusion, Faraday's law and the Extended Finite Element Method (XFEM) were used to simulate chloride diffusion, mass loss from steel corrosion and corrosion product expansion and concrete cover cracking simultaneously, while the pressure due to the tensile stress generated by corrosion product was idealized as radial displacements. Obtained results show an increasing chloride concentration with time, but reduction with depth of penetration, while an obvious crack pattern was obtained.
