Rossi, Emanuele (author), Zhang, Hongzhi (author), Çopuroğlu, Oğuzhan (author), Polder, Rob B. (author), Šavija, Branko (author), Nijland, Timo G. (author)An important input parameter for numerical models that simulate cracking of the concrete cover due to reinforcement corrosion is the Elastic modulus of corrosion product (Ecp). Despite its relevance, Ecp is subject of significant variations according to the values reported in the literature, which vary from less than 100 MPa up to 360 GPa....conference paper 2021

Cats, O. (author), Zhang, C. (author), Nissan, A. (author)Parking pricing policies can be used as a policy instrument to steer the parking market and reduce the externalities caused by traffic in general and parking in particular. A more efficient management of parking demand can improve the utilization of the limited parking capacity at high-demand areas. Even though parking policies are often a topic...conference paper 2015

Gao, L. (author), Zhang, L.M. (author), Chen, H.X. (author)Due to hilly terrain and frequent heavy rainstorms, debris flow is one of the most common and catastrophic hazards in Hong Kong. To mitigate the debris flow risk, prediction of the magnitude and consequence of debris flow is essential. The objective of this paper is to simulate debris flow hazards in a study area in Hong Kong. Assessment of the...conference paper 2015

Zhang, Z. (author), Xiao, Y. (author), Yang, Y. (author), Boom, R. (author), Voncken, J.H.L. (author)Vitrification is considered to be an attractive technology for bottom ash treatment because it destroys the hazardous organics, contributes to immobilization of the heavy metals, and additionally it reduces drastically the volume. The main components of the vitrified bottom ash slag are SiO2 , CaO, Al2 O3 , Fe2 O3 , Na 2 O and MgO, and the...conference paper 2009

Zhang, Y. (author), Ye, G. (author)Concrete is seldom saturated due to its self-desiccation. Even the submerged concrete structures may remain unsaturated for quite a long time. It has been reported the saturation level of pore solution has significant effect on species penetration. However, very little work was proposed regarding the transport properties and serviceability of...conference paper 2014
