Yang, Zhengxian (author), Shi, Peng (author), Zhang, Yong (author), Li, Z. (author)The influences of liquid-binder ratio and mixing sequence on the performance of superabsorbent polymer (SAP)-containing alkali-activated slag (AAS) mortar are investigated in this study. It is found that the SAP absorbs much less liquid in upper supernatant of AAS than in water. Mixing SAP with liquid first induces a larger absorption...journal article 2022

Yang, Sha (author), Ballschmiede, Conrad (author), Gilka-Bötzow, Albrecht (author), Koenders, Eduardus A.B. (author)Low density load bearing structural concrete members with improved thermal insulation properties, composed of lightweight aggregate (LWA) and foam concrete is investigated, which expands the application range of lightweight structural materials. This study aims to characterize a lightweight aggregate concrete with a foamed cementitious matrix ...conference paper 2021

Lantsoght, E.O.L. (author), Zarate Garnica, G.I. (author), Zhang, F. (author), Park, Min-Kook (author), Yang, Y. (author), Sliedrecht, Henk (author)For the assessment of existing slab-between-girder bridges, the shear capacity and failure mode are under discussion. Previous research showed that the static and fatigue punching capacity of the slabs is sufficient as a result of compressive membrane action. The girders then become the critical elements. This research studies the shear capacity...journal article 2021

Liu, Faqi (author), Yang, Hua (author), Yan, R. (author), Wang, Wei (author)The behaviour of square steel tube confined reinforced concrete columns after fire exposure was studied experimentally and numerically in this paper. Eighteen stub columns were first heated following the ISO 834 standard fire including both heating and cooling phases, and were subsequently loaded to failure after cooling to ambient temperature....journal article 2019
