Service Life Estimation of Reinforced Concrete Structures ...

Reinforced concrete structures made using Cr-bearing rebars subject to microcell corrosion were as-sumed with the aim of developing Cr-bearing rebars having the required corrosion resistance in microcell corrosion environments. Their service lives were then estimated for each type of corrosion environment based on a microcell corrosion rate model, and requirements for Cr-bearing rebars to ...

20/02/2014  Corrosion of reinforced concrete structures has become a major problem worldwide, leading to very high repair costs. A dearth of studies has focused on the corrosion damage evolution of reinforced concrete. In this paper, the ultrasonic guided wave (UGW) technique is adopted to monitor the reinforced concrete corrosion damage evolution process. The properties of different guide wave

Understanding the Process of Corrosion in Reinforced Concrete

30/05/2019  The Cost of Concrete Corrosion. Reinforced concrete structures must be tested regularly to detect and prevent corrosion. As these structures get older, the risk of corrosion in reinforcing steel continues to increase. This is especially important since a large number of structures were built using reinforced concrete between the 1950s and 1970s, especially in bridges. In North

Reinforced concrete structures show a very good durability as it is capable of withstanding the different kind of environmental exposure. However, the main limitation of concrete, even of good quality, is that the penetration of chlorides, carbon dioxide (CO 2), moisture, etc., can cause the corrosion of reinforcement bars (rebars). Corrosion of structure can be reduced by proper monitoring ...

Corrosion Resistance in Reinforced Concrete Structures

24/02/2019  Corrosion in reinforced concrete can also occur if the pH of the concrete is decreased. Concrete's naturally high pH, which usually ranges between 12 and 13, creates an environment that promotes the formation and growth of protective oxide films that prevent the dissolution of metal ions.Reducing the pH value of the concrete to as low as 8.5 can cause the passive film to become
