Zhang, Shizhe (author), He, S. (author), Ghiassi, Bahman (author), van Breugel, K. (author), Ye, G. (author)This paper presents an experimental study on the interface bonding properties of polyvinyl alcohol (PVA) fiber in alkali-activated slag/fly ash (AASF) pastes. Three interface bonding properties (i.e., the chemical bonding energy Gd, the initial frictional bond strength τ0, and slip-hardening behavior) were determined using single-fiber pullout...journal article 2023

Zhang, Shizhe (author), Li, Z. (author), Ghiassi, B. (author), Yin, Suhong (author), Ye, G. (author)This study presents a comprehensive experimental investigation on the fracture properties of hardened alkali-activated slag/fly ash (AASF) pastes in relation to the microstructure formation and reaction product composition. The main reaction product in AASF is C-(N-)A-S-H gel along with minor hydrotalcite phase, with the polymerization of C-...journal article 2021

Zhang, Shizhe (author), Zuo, Y. (author), Li, Z. (author), Ye, G. (author)Alkali-activated slag/fly ash (AASF) as an environmental-friendly binder system for construction materials has recently attracted great attention from both academic and industrial communities. Towards its wider engineering application, it is crucial to have a better understanding of the temperature induced effects by different curing regimes and...conference paper 2019
