This paper presents the results of a sensitivity analysis of the diffusion-based corrosion initiation model for reinforced concrete structures built in chloride-laden environments. Analytical differentiation techniques are used to determine the sensitivity of the time to corrosion initiation to the four governing parameters of the model, which include chloride diffusivity in concrete, chloride ...

The causes for the susceptibility of prestressing steels to hydrogen induced stress corrosion and the failure mechanisms occurring could be researched in depth. In contrast to this an exact testing method on the evidence of the prestressing steel sensitivity valid for all steel types does not exist. This has caused not only prejudices against prestressed buildings but has also led to additional...

Speculating about where the future of the field of corrosion prevention, detection, and rehabilitation might lead is interesting—but not without risk. We all are aware of the revolution in electronics, particularly digital electronics, and information science during the past 20 years. We also should recognize that materials science and technology have undergone a major revolution, bringing us n...

Forecasting the life of concrete infrastructures in corrosive environments presents a long-standing and socially relevant challenge in science and engineering. Chloride-induced corrosion of reinforcing steel in concrete is the main cause for premature degradation of concrete infrastructures worldwide. Since the middle of the past century, this challenge has been tackled by using a conceptual ap...

BACKGROUND Noise pollution can contribute to adverse health effects in humans. Noise annoyance and related problems, caused by noise emission during the progress of building construction, have become increasingly important. These problems can influence the exposed workers, as well as vicinity residents. The goal of the present study was to assess the noise annoyance due to noise from constructi...

The rotating cage apparatus is used in the oil industry as a simple and effective test for corrosion. The apparatus generates a large amount of flow induced corrosion and is used by researchers to design effective corrosion inhibitors. While the apparatus is used frequently, the fluid mechanics of the problem is not well understood. Importantly, there is no correct model for the shear stress pr...

The goal of cathodic protection is to prevent corrosion by maintaining buried pipelines at a constant potential with respect to the surrounding soil. In practice, however, the implementation is very complicated since many factors can contribute to the current flowing off the pipe. Design requires characterization of the parameters impacting the corrosion process, such as soil resistivity, size ...

The driving force that causes metals to corrode is a natural consequence of their temporary existence in metallic form. Application of cathodic protection (CP) as measures to stop corrosion has a very long history. The first application of impressed current system for protection of underground structures took place in England and in the United States, about 1910-1912. The first criterion for CP...
