Phan, M.H. (author), Reniers, A.J.H.M. (author), Ye, Qinghua (author), Stive, M.J.F. (author)The coastal zone of Mekong delta is suffering under intense pressures from climate change as well as human intervention. Currently, the coastline evolution of Mekong delta is a complex combination of impacts due to (1) relative sea level rise i.e. the sum of eustatic sea level rise, natural and human induced subsidence (2) sediment transport...conference paper 2017

Ye, M. (author), Lofi, C. (author), Tintarev, N. (author)This paper evaluates whether semantic grouping of reviews helps users make better decisions. Reviews rated as helpful were compared with semantically grouped reviews. While participants did not perceive a reduced effort (using NASA-TLX), they needed less time and performed better on answering questions about the strong,<br/>weak and...conference paper 2017

Zhang, Y. (author), Ye, G. (author)Experiments are carried out to investigate the chloride diffusivity in partially saturated ordinary Portland cement mortars with water-to-cement (w/c) ratios of 0.4, 0.5 and 0.6. Based on resistivity measurement and Nernst-Einstein equation, the chloride diffusivities of cement mortars at various water saturations are estimated. The pore...conference paper 2017

Lukovic, M. (author), Šavija, B. (author), Ye, G. (author), Schlangen, E. (author), van Breugel, K. (author)Corrosion of steel reinforcement is the main cause of deterioration in reinforced concrete structures. It can result in cracking and spalling of the concrete cover. After the damaged cover is repaired, reinforcement corrosion might continue and even accelerate. While the development of the corrosion cell is difficult to control, the damage can...journal article 2017

Zheng, Kunpeng (author), Lukovic, M. (author), de Schutter, Geert (author), Ye, G. (author), Taerwe, Luc (author)This work aims at providing a better understanding of the mechanical properties of the reaction rim in the alkali-silica reaction. The elastic modulus of the calcium alkali silicate constituting the reaction rim, which is formed at the interface between alkali silicate and Ca(OH)2 in a chemically-idealized system of the alkali-silica reaction...journal article 2016

Chen, J. (author), Liu, Xian (author), Ye, G. (author)Microcracks play vital roles in the prediction of the service life of concrete structure. Because microcracks in concrete structure are the preferential ingression channels for aggressive ions, e.g., chloride, sulphate, etc. However, microcracks have potentials to self-heal autogenously due to the continuous hydration of unhydrated cement,...conference paper 2016

Sherzer, G. (author), Gao, P. (author), Ye, G. (author), Gal, E. (author)The heterogeneity of the concrete may be considered on different size scales of observation, ranging from the atomistic scale (10-10m), characterized by the behavior of crystalline particles of hydrated Portland cement, to the macroscopic scale (101 m), where concrete has traditionally been considered homogeneous. The multiscale framework we are...conference paper 2016

Arbi Ghanmi, K. (author), Nedeljković, Marija (author), Zuo, Y. (author), Ye, G. (author)Alkali-activated materials (AAMs) have high potential as alternative binder to ordinary portland cement (OPC), because of their high performance beside lower CO<sub>2</sub> emissions. While there is a general consensus about their strength advantages over OPC, there is a widespread debate regarding their durability. Some groups believe that...journal article 2016
