Non-destructive methods for measuring chloride ingress into concrete: State-of-the-art and future challenges
Chloride ingress is one of the major causes of reinforced concrete (RC) deterioration. Free
chloride induces the corrosion of rebars, reducing the material strength, and therefore, the …

Maintenance planning under imperfect inspections of corroded pipelines
In this paper, a maintenance policy is proposed for pipelines subject to corrosion, by taking
into account imperfect inspection results. The degradation of the pipeline is induced by …
