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
