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

Zheng, T. (author), Guo, Licheng (author), Sun, Ruijian (author), Wang, Tongtong (author), Hong, Changqing (author), Benedictus, R. (author), Pascoe, J.A. (author)In this paper, the effect of interface properties on the compressive failure behavior of 3D woven composites (3DWC) is investigated by incorporating a micromechanics-based multiscale damage model (MMDM). The correlation between the mesoscopic stress of yarns and microscopic stress of constituents is established by defining a stress...journal article 2023

Golchin, A. (author), Guo, Y. (author), Vardon, P.J. (author), Liu, S. (author), Zhang, G. (author), Hicks, M.A. (author)The coupling effect of initial shear stress and thermal cycles on the thermomechanical behaviour of clay concrete and sand-concrete interfaces has been studied. A set of drained monotonic direct shear tests was conducted at the soil-concrete interface level. Samples were initially sheared to half of the material's shear strength and then they...journal article 2023

Mustafa, S. (author), Harrass, Othman (author), Lukovic, M. (author)The number of hybrid concrete structures is increasing due to the need for repairing/strengthening existing structures and the development of new hybrid concrete systems. The structural response of these hybrid structures might be governed by the strength of the interface between the two concretes, making it essential to characterize the...conference paper 2023

Zhang, Shizhe (author)Alkali-activated Materials (AAMs), including those classified as geopolymer, are obtained through the reaction between a solid precursor and an alkaline solution. Compared with ordinary Portland cement (OPC) binders, these materials maintain comparable mechanical properties but have the advantage of reducing greenhouse gas emissions and...doctoral thesis 2022

Kiss, A.A. (author), Grievink, J. (author)Process Systems Engineering (PSE) is a discipline that deals with decision-making, at all levels and scales, by understanding any complex process system using a holistic view and a systems thinking framework. A closely related discipline (considered usually a part of PSE) is the Computer Aided Process Engineering (CAPE) which is a...journal article 2020

(author), Bedeaux, Dick (author), Kjelstrup, Signe (author)It is known that thermodynamic properties of a system change upon confinement. To know how, is important for modelling of porous media. We propose to use Hill’s systematic thermodynamic analysis of confined systems to describe two-phase equilibrium in a nanopore. The integral pressure, as defined by the compression energy of a small volume,...journal article 2020
