Polder, R.B. (author), Pan, Yifan (author), Courage, Wim (author), Peelen, Willy H A (author)Maintenance costs of reinforced concrete infrastructure (bridges, tunnels, harbours, parking structures) are increasing due to aging of structures under aggressive exposure. Corrosion of reinforcement due to chloride ingress is the main problem for existing structures in marine and de-icing salt environments. Corrosion cannot be ruled out...journal article 2016

Chen, Zhipei (author), Koleva, D.A. (author)Stray current circulating in reinforced concrete structures may initiate corrosion or accelerate existing corrosion processes on embedded reinforcement. In some cases, the range of dangerous or unwanted interactions of stray currents under favorable conditions (environment), is much broader than is generally recognized. All these show that...journal article 2016

Laird, Jamie S. (author), Hughes, Anthony E. (author), Ryan, C.J. (author), Visser, P (author), Terryn, H.A. (author), Mol, J.M.C. (author)Lithium based inhibitors in aerospace coatings are seen as excellent replacements for their chromium counterparts which are both carcinogenic and heavier. However, Li is generally difficult to detect and following changes in its distribution due to corrosion is impossible with many standard techniques. Combining MeV Particle Induced Gamma and...journal article 2017

Yang, Z. (author), Polder, R.B. (author), Mol, J.M.C. (author)Owing to the unique molecular structure and high ion exchange capacity, hydrotalcites are believed to have a potential to be modified and tailor-made as an active corrosion protective component of reinforced concrete. In this paper, two types of modified hydrotalcites (MHT-pAB and MHT-NO2) were tested both in alkaline solution and mortar for...journal article 2017

Mustaffa, Z. (author), van Gelder, P.H.A.J.M. (author), Dawotola, A. W. (author), Yu, S. Y. (author), Kim, D. K. (author)This paper presents a method for assessing the reliability of a corroded pipeline placed in series, with special consideration given to the effect of the length scale imposed by each segment of the pipe. The features of corrosion in different pipe segments are statistically correlated; thus, a failure in one section may impact the adjacent...journal article 2018

Koleva, D.A. (author)The corrosion of reinforced steel, and subsequent reinforced concrete degradation, is a major concern for infrastructure durability. New materials with specific, tailor-made properties or the establishment of optimum construction regimes are among the many approaches to improving civil structure performance. Ideally, novel materials would...journal article 2018
