Special Issue Information

Dear Colleagues,

Reinforcement corrosion is the most relevant deterioration process in reinforced concrete structures and the top cause for their failure. Early deterioration brings direct and indirect economical losses, as repair costs and deprivation of use, respectively. It is known that decisions taken within the frame of structures design have a significant impact on the existing resources.

Therefore, durability is among the most investigated subjects in construction science and the current trend is towards performance-based design through service life design. Such an approach requires prediction models for the deterioration mechanisms. It is widely accepted that the deterioration caused by reinforcement corrosion comprises two stages: initiation and propagation. For the initiation period, there are already well-established models. However, the same cannot be said for the propagation period.

This Special Issue of Applied Sciences provides a forum for original studies and comprehensive reviews on the modeling of corrosion mechanisms in reinforced concrete that considers extrapolation from experimental/accelerated tests, empirical models, analytical models or numerical models. Furthermore, studies addressing the influence of the environment (carbonation-induced corrosion or chloride-induced corrosion), of supplementary cementitious materials, and of aggregate source (natural or recycled) are welcome.

Interests:

design for durability, as one of the main parameters of sustainability; agreed methods to assess the durability of existing reinforced concrete structures; reliable methods to make appropriate provisions for maintenance of reinforced concrete structures; improvement of sustainability analyses based on life cycle assessment, life cycle management, life cycle design or life cycle cost.

Rebar Shape Time-Evolution During a Reinforced Concrete Corrosion Test: An Electrochemical Model

An electrochemical model is presented to calculate the rebar shape time-evolution in reinforced mortar specimens during forced corrosion tests. This provides a more realistic description than the usually used geometric models. The current distribution along the rebar perimeter is calculated by using Finite Element Method (FEM) to solve Laplace equation. Then, Faraday’s law is used to relate current distribution to rebar volume increase due to corrosion products creation. The shape of the rebar section is obtained as a function of corrosion time.
