Corrosion-induced damages and failures of posttensioned bridges: A literature review
Menga, Antonia; Kanstad, Terje; Cantero, Daniel; Bathen, Lise; Hornbostel, Karla; Klausen, Anja Birgitta Estensen (Peer reviewed; Journal article, 2022)Corrosion of posttensioned bridges raises great concern, since the only way to safely assess the condition of the tendons is through destructive evaluation. In this scenario, this paper presents the results of an extensive ... -
The cracking risk of hardening concrete exposed to realistic curing temperature regimes and restraint conditions – Experimental investigations of important parameters
Klausen, Anja Birgitta Estensen; Kanstad, Terje; Bjøntegaard, Øyvind (Peer reviewed; Journal article, 2022)Early age cracking in hardening concrete can be evaluated using dedicated calculation methods. Such calculations require a wide selection of input parameters, e.g. autogenous- and thermal deformation, hydration heat ... -
Early age autogenous shrinkage cracking risk of an ultra-high performance concrete (UHPC) wall: Modelling and experimental results
Kheir, Judy; Klausen, Anja Birgitta Estensen; Martius-Hammer, Tor Arne; De Meyst, Laurence; Hilloulin, Benoit; Van Tittelboom, Kim; Loukili, Ahmed; De Belie, Nele (Peer reviewed; Journal article, 2021)Ultra-High Performance Concrete (UHPC) exhibits high autogenous shrinkage (AS) which significantly increases the risk of early age cracking. To predict the risks of early age shrinkage cracking of environmentally friendly ... -
Early age crack assessment of concrete structures: Experimental and theoretical approaches
Klausen, Anja Birgitta Estensen; Kanstad, Terje; Bjøntegaard, Øyvind (Chapter, 2017)The present paper contains a brief overview of work performed within the Ph.D. thesis "Crack assessment of concrete structures: experimental investigation of decisive parameters" (2010 – 2016). The main objective of the ... -
The effect of curing temperature on autogenous deformation of fly ash concretes
Klausen, Anja Birgitta Estensen; Kanstad, Terje; Bjøntegaard, Øyvind; Sellevold, Erik Johan (Peer reviewed; Journal article, 2020)For concrete subjected to restrained conditions, autogenous deformation (AD) and thermal dilation (TD) are the main driving forces behind stress development in the hardening phase. Generally, AD in concrete is modelled by ... -
The effect of shrinkage reducing admixtures on drying shrinkage, autogenous deformation, and early age stress development of concrete
Klausen, Anja Birgitta Estensen; Kanstad, Terje (Peer reviewed; Journal article, 2021)The current study investigates the effect of shrinkage reducing admixtures (SRA) on volume changes that may lead to shrinkage cracking and early age cracking. Drying shrinkage (DS) and autogenous deformation (AD), the ... -
Fatigue Capacity of Concrete Subjected to Partially Loaded Areas
Afaghi, Mohammad; Klausen, Anja Birgitta Estensen; Overli, Jan Arve (Chapter, 2022)The compressive strength of concrete at bearing areas is increased due to the confinement of surrounding concrete and reinforcement. In these partially loaded areas, local crushing and transverse tension forces must be ... -
Hardening Concrete Exposed to Realistic Curing Temperature Regimes and Restraint Conditions: Advanced Testing and Design Methodology
Klausen, Anja Birgitta Estensen; Kanstad, Terje; Bjøntegaard, Øyvind (Journal article; Peer reviewed, 2019)Early age cracking (EAC) is a well-known problem area when it comes to concrete structures. The driving forces behind EAC are thermal dilation and autogenous deformation, but EAC is also strongly dependent on material and ... -
Impact of super absorbent polymers on early age behavior of high performance concrete walls
Kheir, Judy; De Meyst, Laurence; Filho, Jose; Martius-Hammer, Tor Arne; Klausen, Anja Birgitta Estensen; Hilloulin, Bernard; Loukili, A.; De Belie, Nele (Chapter, 2021)The prediction of the early age behavior of cementitious materials is a difficult task, because many of the material properties are very sensitive to curing conditions as it is the case for High Performance Concrete (HPC), ... -
