Dieterich Murr, Laura (author)The Netherlands is currently facing a significant challenge regarding its highway system due to the rise in traffic, especially in densely populated areas like The Randstad. However, constructing new infrastructure or replacing old bridges is not a practical solution due to environmental concerns. Most of the country's prestressed concrete...master thesis 2023

Lantsoght, E.O.L. (author)One of the barriers to implementation of steel fiber reinforced concrete (SFRC) into structural applications is the lack of understanding of the shear behaviour of SFRC members. This paper proposes a theoretical model for the shear capacity of SFRC members with mild steel reinforcement based on the shear-carrying mechanisms and sectional...journal article 2023

Prosperi, A. (author), Longo, M. (author), Korswagen, Paul A. (author), Korff, M. (author), Rots, J.G. (author)This study aims to investigate the damage response of unreinforced masonry (URM) façades resting on strip foundations and subjected to ground settlements via numerical models. The models depict the non-linear constitutive behaviour of both the masonry, via smeared cracking, and of the soil-foundation interaction, via nonlinear interface...journal article 2023

Li, Z. (author), Chen, Y. (author), Provis, John L. (author), Cizer, Özlem (author), Ye, G. (author)This paper provides a critical review on autogenous shrinkage of alkali-activated slag (AAS). It is reported that AAS paste, mortar, and concrete generally show larger autogenous shrinkage than Portland cement (PC) counterparts. Self-desiccation is the main driving force of the autogenous shrinkage of hardened AAS, but other mechanisms also...review 2023

Sood, A. (author), Schimmel, Jim (author), Mattos Ferreira, V. (author), Bosman, Marko (author), Goulas, Constantinos (author), Popovich, V. (author), Hermans, M.J.M. (author)Invar alloys exhibit low thermal expansion and are useful in applications requiring dimensional stability when subject to temperature changes. Conventional production of Invar faces certain challenges that can be offset by exploiting additive manufacturing processes. This study employed pulsed gas tungsten arc welding (GTAW) to deposit Invar...journal article 2023

Baloch, Hassan (author), Grunewald, S. (author), Matthys, Stijn (author)There is a need to develop innovative repair materials which can overcome the challenges of cement-based repair mortars being relatively prone to shrinkage effects. In practice, free shrinkage of repair mortar is often considered as an indicator for potential cracking and delamination of applied repair mortars due to restrained shrinkage...journal article 2023

Kraaijenbrink, Lennart (author)With the rise of hydrogen as a green alternative for fossil fuels, the demand for storage capacity of hydrogen increases significantly. Due to the high risk of explosions in urban environments it brings along, the blast analysis of buildings within in range of the explosions becomes more relevant.<br/><br/>The goal of this research is to develop...master thesis 2022

Mustafa, S. (author), Singh, S. (author), Hordijk, D. (author), Schlangen, E. (author), Lukovic, M. (author)Hybrid application of conventional concrete and Strain Hardening Cementitious Composite (SHCC) is recently shown to be promising for crack width control. In this paper, a combined experimental and numerical study is performed to validate the concept and to study the effect of interface treatment on crack width control. The interface is varied...journal article 2022

Li, Z. (author), Liang, X. (author), Liu, C. (author), Liang, M. (author), van Breugel, K. (author), Ye, G. (author)This study investigates the deformation of free and stress of restrained alkali-activated slag concrete (AASC), respectively, under semi-adiabatic condition. The concrete shows first thermal expansion, which is compensated soon by autogenous shrinkage. The subsequent cooling down of the concrete aggravates shrinkage and development of tensile...journal article 2022

Matos, Ana Mafalda (author), Nunes, Sandra (author), Chaves Figueiredo, S. (author), Schlangen, E. (author), Aguiar, José L.Barroso (author)The subject of this paper is the extent to which, during wetting–drying cycles, chloride ions can penetrate Ultra-high-Performance Fibre Reinforced Cementitious Composites (UHPFRC) specimens subjected to combined mechanical and environmental load. Pre-cracking was obtained by subjecting prismatic specimens (40 × 40 × 60mm<sup>3</sup>) to four...book chapter 2021

Li, Z. (author), Zhang, Shizhe (author), Liang, X. (author), Kostiuchenko, A. (author), Ye, G. (author)Alkali activated concrete (AAC) has not received broader industry acceptance, one reason of which lies in the uncertainties in the durability against shrinkage and potential cracking. Many studies reported that AAC exhibit larger autogenous shrinkage than OPC concrete. However, it is unable to deduce that AAC should show higher cracking...book chapter 2021

Yan, Xu (author)Structures may be subjected to both mechanical loads and imposed deformation. On one hand, the mechanical loads include, for example, the self-weight of the construction work, the action from normal use by person, furniture and movable objects, vehicles, snow, wind, execution, etc. On the other hand, when the deformation of a structure is...master thesis 2020

(author)In this study, internal curing by superabsorbent polymers (SAP) is utilized to mitigate self-desiccation and autogenous shrinkage of alkali-activated slag (AAS) pastes. Absorption and desorption kinetics of SAP incorporated in AAS pastes were studied with X-ray tomography. Internal curing delayed the peak of the rate of heat liberation but...journal article 2020
