SUSTAINABILITY ASSESSMENT OF CONCRETE STRUCTURE DURABILITY UNDER REINFORCEMENT CORROSION
Abstract eng: In the present paper a parametric study is conducted based on an existing finite element based model. The influence of cover layer, reinforcement diameter and water-to-cement ratio is compared to a possible scatter in the results due to insufficient knowledge about the distribution of the corrosion current density along the circumference of the reinforcement. Simulations show that the scatter has a greater influence on the results than changing the parameters wherefore it is concluded that further investigation of the non-uniform deposition of corrosion products is essential to better understand and predict the durability of a given structure.
