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), Duque-Redondo, Eduardo (author), Kostiuchenko, A. (author), Sanchez Dolado, J. (author), Ye, G. (author)This paper aims to study the adhesion mechanism of polyvinyl alcohol (PVA) fiber within alkali-activated slag/fly ash (AASF) matrix using molecular dynamics (MD) simulation in combination with systematic experimental characterization. The adhesion of PVA to C-(N-)A-S-H gel with different Ca/(Si+Al) and Al/Si ratios was modeled using MD...journal article 2021
