Sun, Yubo (author), Chen, Boyu (author), Zhang, Shizhe (author), Blom, Kees (author), Luković, Mladena (author), Ye, Guang (author)In recent years, the rapid industrialization and urbanization led to the explosive growth of municipal solid waste incineration (MSWI) bottom ashes (BA) production. However, most of them are directly landfilled, which not only brings environmental burden but also results in loss of potential resources. Present researches have proved that MSWI BA...conference paper 2021

Qiu, Xiujiao (author), Chen, Jiayi (author), Ye, Guang (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

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

Chen, Jing (author), Liu, X. (author), Zeng, Xiao Liang (author), Ye, Huai Yu (author), Zhang, Kouchi (author)Hexagonal boron nitride (BN) is often used as filler to improve the thermal conductivity of polymer matrix due to its high thermal conductivity. However, previously reported BN-based composites always have a high in-plane thermal conductivity, which is not beneficial for vertical heat dissipation. In addition, high BN content results in the...journal article 2022
