PhD positions: Multimodal X-ray and neutron imaging of steel corrosion in concrete

PhD positions: Multimodal X-ray and neutron imaging of steel corrosion in concrete

At the Institute for Building Materials (IfB) – Department of Civil, Environmental and Geomatic Engineering – in Switzerland. In collaboration with the Paul Scherrer Institut (PSI), EPFL, and Haute Ecole Arc Conservation-restauration (HE-ARC CR) (Switzerland).

Starting date: March 2021.

Based on encouraging recent progress made in multimodal imaging, we aim to develop and validate a cutting-edge X-ray and neutron computed tomography method, tailored for the in-situ study of corrosion phenomena in opaque porous media. In combination with well-proven corrosion science methods, this novel imaging technique will allow the development of a new experimental approach to study corrosion processes in opaque media, such as steel corrosion in concrete or soil. These positions are in the context of a wider project, including various students and senior scientists working in multimodal imaging (PSI), conservation and archaeology (HE-ARC CR), and corrosion science (EPFL, ETH Zurich).

The project will be performed in the research group of Prof. Dr. Ueli Angst at the Institute for Building Materials (D-BAUG) at ETH Zurich, Switzerland. Extended scientific visits to PSI are planned.

The aimof this project is to utilize the new approach described above to fundamentally study the mechanism of corrosion in concrete. This includes studying the effects of macroscopic voids at the steel/concrete interface and of their moisture state as well as quantifying in-situ and over time the transport and precipitation of corrosion products in the cementitious matrix upon reinforcing steel corrosion. The project will be primarily of experimental nature and involve techniques from corrosion science, electrochemistry, concrete technology, and X-ray and neutron computed tomography. The work will closely interface with other activities in this project, in particular, imaging work will be carried out at PSI.

We are looking for two PhD candidates. The projects are fully financed for 4 years, including  salary acc. to the employment conditions of ETH Zurich (coverage of living expenses).

Successful applicants should hold a MSc degree preferably in corrosion science, materials science, civil engineering or related areas. Previous experience and knowledge in corrosion is needed, and the candidate is expected to show a strong interest in cement and concrete science as well as microstructural characterization and imaging. Proficiency in written and oral English as well as maturity and self-motivation are necessary. Above all, candidates should be curious and enthusiastic in what they do.
