PhD Position in Moisture Transport in Carbonated Cementitious Materials

100%, Zurich, fixed-term

We are offering a fully-funded position for a motivated and talented PhD candidate to join the Durability of Engineering Materials research group at ETH Zurich, Switzerland. The research group ’Durability of Engineering Materials’ at the Institute for Building Materials (Department of Civil, Environmental and Geomatic Engineering) at ETH Zurich performs research at the interface of material’s science, corrosion science and engineering. Our mission is to deliver the scientific basis needed to ensure safety, durability and sustainability of our civil infrastructures.

The position is expected to start in early 2025 and is fully funded for 4 years.

Job description

It is well known that reinforcing steel corrosion in carbonated concrete is highly dependent on the internal moisture condition. Therefore, to mitigate steel corrosion, especially in environmentally friendly cement types, there is an urgent need to understand moisture transport in carbonated concrete and to control the water content at the steel-concrete interface. Previous studies reported that moisture transport in carbonated cementitious materials is different from non-carbonated cementitious materials because of the different microstructural stability under the variations of moisture content.

This PhD project includes the experimental characterisation of microstructure and moisture transport properties of carbonated and non-carbonated cementitious materials. Both established, state-of-the-art and advanced experimental techniques will be applied. This project will be in collaboration with numerical modelers in the research group. Experimental data will be used to feed, calibrate and validate moisture transport models.

Profile

Profile of successful applicants

• MSc degree in civil engineering, materials science, chemical engineering, earth science or geochemistry
