Sun, Y. (author), Chen, B. (author), Zhang, Shizhe (author), Blom, C.B.M. (author), Lukovic, M. (author), Ye, G. (author)With the development of waste recovery techniques, previous research has revealed that coarse fractions of municipal solid waste incineration (MSWI) bottom ash (BA) after proper treatment could be applied in the construction sector, while the fines are seldom recovered in practice and normally landfilled. This study explores the potential...journal article 2024

Rostami, R. (author), Klemm, A.J. (author)The use of Supplementary Cementitious Materials (SCMs) in concrete manufacture has significantly increased in the last decades mainly due to their sustainability benefits. Polymeric Fibres (PF) are commonly used in concrete in order to enhance adhesive and frictional bond with a cementitious matrix and improve mechanical properties. Despite...conference paper 2021

Scrivener, Karen (author), Georget, Fabien (author), Wilson, William (author), Sui, Shiyu (author)Cementitious Materials become more diverse. In particular, to reduce the CO2 emissions associate with production, it is necessary to increase the levels of replacement of clinker by other materials. A critical consideration is to know how durable different materials will be. Most forms of degradation involve the ingress of different species into...conference paper 2021

Zhuang, Shiyu (author), Wang, Qiang (author)Water absorption is an indicator of other transport properties and even durability of concrete since it provides a dominant invasion mechanism for the penetration of aggressive ions. Relationship between the water absorption and the chloride ion penetration of concrete containing fly ash, slag and silica fume at various water-to-binder ratios is...conference paper 2021

Phung, Quoc Tri (author), Seetharam, Suresh .C. (author), Ferreira, Eduardo (author), Govaerts, Joan (author), Hendrix, Katrien (author), Valcke, Elie (author)This paper presents an extension of an existing phenomenological model for predicting the evolution of hydration heat of a cemented waste form. The cemented waste form is essentially a mixture of blended cement and homogeneous low- and intermediate-level liquid (simulant) radioactive waste (sludge). The motivation stems from the fact that the...conference paper 2021
