Zhang, Zhidong (author), Angst, Ueli M. (author)The structure of concrete, in particular the microstructure of the steel-concrete interface (SCI), can significantly affect corrosion of rebars. To support corrosion, oxygen needs to diffuse from the ambient environment to the steel surface. Meanwhile, corrosion products transport through the SCI and precipitate in concrete. Transport properties...conference paper 2021

Okur, Ö. (author)In order to limit the amount of greenhouse gas emission, transitioning to renewable energy sources (RES) is critical. However, integrating RES in the existing power system is not straightforward since RES possess variable and uncertain characteristics. Due to these characteristics, as the penetration of RES increases, maintaining the balance...doctoral thesis 2021

Qiu, Xiujiao (author), Chen, J. (author), Ye, G. (author), De Schutter, Geert (author)ASR (alkali-silica reaction) is one of the toughest durability problems in engineering. However, the damage induced by ASR is still fairly unpredictable due to the lack of microstructural information of cement-based materials affected by ASR, while the microstructure determines the global performance. In order to fill this gap, a multiscale...conference paper 2021
