(Master thesis, 2021)Abstract will be available on 2024-06-29 -
The behavior of hydrophobic-core/hydrophilic-shell structured microgels at an interface: From Mickering emulsion to colloidosomes with dual-level controlled permeability
(Journal article; Peer reviewed, 2016)A bottom-up approach was empolyed to prepare colloidosomes with dual-level controlled permeability. Starting from the monodisperse poly-2,2,2-trilfuoroethyl methacrylate (PTFMA) core, different size of microgels were ... -
The Coupling Effect of Lead and Polishing Treatments on the Passive Films of Alloy 690TT in High-Temperature and High-Pressure Water
(Journal article; Peer reviewed, 2019)In pressurized water reactors, the existence of lead contamination can promote the corrosion of Alloy 690TT. During the manufacturing, transportation, and assembly processes, Alloy 690TT surface is easily scratched and it ... -
The Digital Workflow of Parametric Structural Design - Developing Grid Shells in a Nordic Climate
(Master thesis, 2018)Unusual shapes are becoming more and more prevalent in the cityscape, however they often rely on large and complex configurations of material. New and empowered digital tools - parametric modelling software - allow for ... -
The effect of accelerated ASR on the mechanical properties and degree of damage of concrete over time - with and without uniaxial compressive stress
(Master thesis, 2018)The aim of this master thesis is to investigate the effect on mechanical properties and degree of damage in concrete exposed to accelerated Alkali-silica reaction (ASR) and uniaxial com-pressive stress, and test if the ... -
The effect of artificial leaching with HCl on chloride binding in ordinary Portland cement paste
(Journal article; Peer reviewed, 2020)This study investigates how the pH in the pore solution influences the chloride binding in Portland cement pastes. Cement paste samples were exposed to NaCl, CaCl2 and HCl solutions. The mechanisms of changes in chloride ... -
The effect of calcium lignosulfonate on ettringite formation in cement paste
(Journal article; Peer reviewed, 2018)The effect of a softwood calcium lignosulfonate, LSs, on the ettringite formed in cement paste was investigated. Two Portland cements, mainly differing in surface area and C3A content, were used. The effect of LSs addition ... -
The Effect of Fiber Reinforcement on Crack Development due to Restraint of Concrete Structures
(Master thesis, 2016)This thesis studies the effect of fiber reinforcement on crack development in concrete structures. Background for choice of subject, is that cracks due to external restraint are observed on many of today's bridges, and it ... -
The Effect of Fibres on the Compressive Ductility of Lightweight Aggregate Concrete
(Master thesis, 2013)The purpose of this thesis was testing the effect of different type of fibre reinforcements to the compressive ductility of lightweight aggregate concrete (LWAC). Concrete with density of about 1800 kg/m3 and compressive ... -
The effect of ice type on ice adhesion
(Journal article; Peer reviewed, 2019)To lower the ice adhesion strength is the most efficient technique for passive ice removal for several applications. In this paper, the effect of different types of ice on the ice adhesion strength was investigated. The ... -
The effect of realistic curing temperature on the strength and E-modulus of concrete
(Journal article; Peer reviewed, 2018)The strength and E-modulus of concrete are decisive parameters when it comes to ultimate limit state design, serviceability limit state design, and early age crack assessment. The properties of concrete are generally ... -
The effect of reinforcement corrosion on the structural behaviour of prestressed bridges in the Norwegian coastal regions
(Chapter, 2017)Prestressed concrete (PC) is one of the main structural materials used in Norway for bridge structures. Prestressed and precast concrete beams were even used for building the historical Atlantic Road, which has the status ... -
The effect of the steel-concrete interface on chlorideinduced corrosion initiation in concrete: a critical review by RILEM TC 262-SCI
(Journal article; Peer reviewed, 2019)The steel–concrete interface (SCI) is known to influence corrosion of steel in concrete. However, due to the numerous factors affecting the SCI—including steel properties, concrete properties, execution, and exposure ... -
The Effects of Near-fault Earthquakes On a High-rise Structure In The Oslo Area
(Master thesis, 2012)The objective of the presented research is to evaluate the seismic response of a high-rise structure located in a seismic environment. For this purpose, the Oslo Plaza building located in Oslo, Norway, was chosen. A numerical ... -
The Effects of Numerical Modeling Assumptions in Seismic Design
(Master thesis, 2018)Complex numerical models have been developed during the last decades. They are able to model complex phenomena that may occur in a structure when subjected to seismic excitations, including nonlinear material response and ... -
The Function of Form: Conceptual Design of Modern Shell Structures
(Master thesis, 2013)Concrete shells were a hit at the middle of the nineteenth century, but have since decreased in popularity. Landmark buildings of recent years may indicate that curved shells are again in vogue among architects. Shell ... -
