“…Corrosion modeling of reinforcing steel is one of the methods that has been gaining increasing interest in the last two decades [4,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. Modeling the corrosion process will allow the assessment of the current state of the existing RCS, improve the stability and help to extend the service life of RCS.…”

“…Modeling the corrosion process will allow the assessment of the current state of the existing RCS, improve the stability and help to extend the service life of RCS. Most of the models developed are related to the penetration of Cl − , therefore with the initiation phase of corrosion [26,28,[31][32][33][34].…”

Several methods for corrosion monitoring of reinforced concrete structures (RCS) have been proposed in the last few decades. These systems may be used either in new, existing or repaired structures. The corrosion monitoring can be performed by different methodologies. These may or may not be destructive, use different degrees of complexity and cost, and provide information on the progression and kinetics of the corrosion phenomena. The destructive methods are limited to sampling. Therefore, these may not be representative of the whole structure, which is extremely important in RCS with large heterogeneities both in terms of materials used and in terms of the exposure environment. Within this context, non-destructive methods have been widely developed, which are intended to provide quick information about the entire structure. Ideally, these systems should be able to detect the corrosion state of the steel inside the concrete, the main causes of corrosion and the evolution of corrosion phenomena over time. This manuscript reviews and summarizes the actual state of the art and the main achievements in the field of electrochemical sensors based on non-destructive methods for corrosion monitoring of RCS in the last few years. The challenges and perspectives in this field will also be discussed.

“…The cover depth, diffusion coefficient, and critical chloride content with each random variable (i.e., mean, Coefficient of Variation COV) are usually adopted for the evaluation of failure probability [51][52][53][54]. Currently, several actual durability designs have been attempted for large RC structures; however, this process has not been widely performed [55,56].…”

Abstract:Concrete is considered to be a construction material with high durability and excellent fire resistance. However, degradation occurs, leading to structural safety problems and expensive maintenance costs. Currently, durability design and its concepts are provided in the concrete specifications and structural design codes in many countries, but they vary in terms of the design methodologies and users' demands. Reinforced concrete (RC) structures based on a reasonable durability design with a quantitative procedure can prevent unnecessary maintenance expenses and reduce environmental loads. This paper presents the current trends of durability design in South Korea and government support for infrastructure. In this work, the two representative durability design philosophies (deterministic and probabilistic approaches) are briefly summarized, and the current guidelines and related requirements for durability design in several countries are investigated. Durability design is now changing from simple material requirement control to performance-based design with quantitative parameters considering various exposure classifications and evaluation processes. RC structures based on reasonable durability design can make a great contribution to reducing maintenance costs and environmental effects like CO 2 emissions.
