Abstract

In the present paper a finite element model is introduced to simulate corrosion-induced damage in concrete. The model takes into account the penetration of corrosion products into the concrete as well as non-uniform formation of corrosion products around the reinforcement. To ac- count for the non-uniform formation of corrosion products at the concrete/reinforcement interface, a deterministic approach is used. The model gives good estimates of both deformations in the con- crete/reinforcement interface and crack width when compared to experimental data. Further, it is shown that non-uniform deposition of corrosion products affects both the time-to cover cracking and the crack width at the concrete surface.
