Offer Description

The Institute of Building Materials Research (ibac) at RWTH Aachen Universityis seeking a highly motivated graduate student or PostDoc to contribute to our ERC synergy project FatResCon – concrete matrices for high-cycle fatigue eco-efficient infrastructure. You will be part of an international, multi-disciplinary team of 22 researchers at RWTH Aachen University, Brno University of Technology, and TU Wien (Vienna University of Technology) to investigate the nano- and microstructural origins of high-cycle fatigue of concrete in order to predict the long-term performance of engineering structures.

The team at ibac conducts research with the aim to predict the role of hydration with a focus on the impact of load dependent water redistribution as function of binder chemistry. A PhD candidate will investigate the microstructural and mineralogical changes of the interfacial transition zone (ITZ) between aggregates and paste, as well as steel and paste of selected eco-efficient binder systems. Synthetic ITZ samples will be assessed in details by means of mechanical, physical and chemical properties. SEM-EDX analyses will provide insights into microstructural evolution. This research aims to generate missing data on the ITZ of different eco-efficient concretes to enhance upscaling efforts as input for micromechanical models.

We are looking for a civil engineer with good background on materials science, a materials scientist, mineralogist or similar with an interest in establishing links between mechanical and physico-chemical properties of cementitious systems.
