Tensile Mechanical Characteristics of Thinnest Carbon Sulfur Nanothreads in Orientational Order
(Peer reviewed; Journal article, 2021)Carbon sulfur nanothreads (CSNTs) mainly composed of two chiral long alkane chains have been recently fabricated from thiophene by a pressure-induced phase transition in low-temperature, but their mechanical properties ... -
Load effects in reinforced concrete beam bridges affected by alkali–silica reaction—Constitutive modelling including expansion, cracking, creep and crushing
(Peer reviewed; Journal article, 2021)Material modelling, from the micro to the macro level, of concrete affected by alkali–silica reaction (ASR) has been devoted a lot of research. However, the application of the material models in structural analyses of ... -
Gels as emerging anti-icing materials: a mini review
(Peer reviewed; Journal article, 2021)Gel materials have drawn great attention recently in the anti-icing research community due to their remarkable potentials for reducing ice adhesion, inhibiting ice nucleation, and restricting ice propagation. Although the ... -
Effect of pre-stretching on the mechanical behaviour of three artificially aged 6xxx series aluminium alloys
(Peer reviewed; Journal article, 2021)The effect of pre-stretching on the mechanical behaviour of the aluminium alloys AA6063, AA6061 and AA6110 in temper T6 has been investigated. Uniaxial tensile tests and quasi-static axial crushing tests were conducted on ... -
Dynamic anti-icing surfaces (DAIS)
(Peer reviewed; Journal article, 2021)Remarkable progresses have been made in surface icephobicity in the recent years. The mainstream standpoint of the reported anti-icing surfaces yet only considers the ice-substrate interface and its adjacent regions being ... -
The combined effect of potassium, sodium and calcium on the formation of alkali-silica reaction products
(Peer reviewed; Journal article, 2020)Both alkalis and calcium play essential roles in the formation of alkali-silica reaction (ASR) products. Investigation of their combined effect helps to better understand the conditions of ASR. In this study, samples with ... -
Shape and Size of Particles Scaled from Concrete Surfaces during Salt Frost Testing and Rapid Freeze/thaw in Water
(Peer reviewed; Journal article, 2021)Thickness (T), Length (L), Width (W) and size distribution of scaled concrete particles in frost testing were measured. T (mm) increases with particle size surprisingly similarly for different concrete qualities and frost ... -
A novel tests set-up for validation of connector models subjected to static and impact loadings
(Peer reviewed; Journal article, 2021)A novel test set-up is presented for validation of hybrid connector models between steel and aluminium components subjected to static and impact loading. The proposed components consisted of two hat profiles in steel and ... -
Non-linear behaviour of insufficiently grouted posttensioned concrete members
(Master thesis, 2021)Denne masteroppgaven har som mål å undersøke de konstruksjonstekniske effektene av manglende mørtel i etteroppspente betongkonstruksjoner. Dette ble gjort ved å gjennomføre ikke-lineære analyser i elementmetodeprogrammet ... -
Synthesis, characterization, and thermodynamic study of selected Na-based zeolites
(Peer reviewed; Journal article, 2020)Zeolites are crystalline aluminosilicates with three-dimensional framework structures that can form in alkali-activated cements, Roman cements, and the interaction zone of cements and clays. However, their stability domains ... -
Field Station Sandnessjøen, Effect of cracks in concrete after 25 years - Data report
(Research report, 2020)Tre opprissede betongbjelker støpt med forskjellige bindemiddelsammensetninger ble undersøkt etter 25 års marin eksponering ved feltstasjon Sandnessjøen. Betongbjelkene ble undersøkt med tanke på effekten av riss på ... -
Beregningsregler for slanke betongsøyler
(Master thesis, 2021)Det arbeides med en ny revisjon av dagens standard for betongkonstruksjoner, og i denne oppgaven har nåværende og revidert standard blitt sammenlignet gjennom en parameterstudie. Bakgrunnslitteratur for aktuelle tema er ... -
Thermodynamic study of cement/rock interactions using experimentally generated solubility data of zeolites
(Peer reviewed; Journal article, 2020)Alteration of widespread interfaces between cements and clays in geological time scales is essential to the safety assessment of radioactive waste repositories but not well understood partly due to the low reliability of ... -
The effect of sodium hydroxide on Al uptake by calcium silicate hydrates (C-S-H)
(Peer reviewed; Journal article, 2020)To reduce the CO2 emissions from cement production, Portland cement (PC) is partially replaced by supplementary cementitious materials (SCM). Reactions of SCM with PC during hydration leads to the formation of Csingle ... -
Fatigue of Concrete
(Master thesis, 2021)Stadige fremskritt innenfor betongteknologi muliggjør bygging av slankere og mer materialeffektive konstruksjoner enn tidligere. Ved økt slankhet blir også påvirkningen fra sykliske laster viktigere og utmattingskapasiteter ... -

On the importance of tunica intima in the aging aorta: a three-layered in silico model for computing wall stresses in abdominal aortic aneurysms
(Peer reviewed; Journal article, 2020)Layer-specific experimental data for human aortic tissue suggest that, in aged arteries and arteries with non-atherosclerotic intimal thickening, the innermost layer of the aorta increases significantly its stiffness and ... -
Carbonation resistance of concrete and mortar containing novel low clinker cement
(Student paper, others, 2019)Corrosion of reinforcement steel is a major deterioration mechanism for reinforced concrete structures. Corrosion can be caused by the carbonation of concrete. In this report we test the carbonation resistance of a novel ... -
Thermal transport in polyethylene: The effect of force fields and crystallinity
(Peer reviewed; Journal article, 2021)In this article, we study the local structure and heat transfer properties (thermal conductivity and interfacial conductance) in model semi-crystalline Polyethylene (PE) by non-equilibrium molecular dynamics. We compare ...
