Freeze-thaw damage evaluation and model creation for concrete exposed to freeze–thaw cycles at early-age
(Peer reviewed; Journal article, 2021)Concrete subjected to freeze–thaw cycles action at early-age will suffer serious physical damage, resulting in degradation of the concrete’s performance. The subsequent curing conditions after early-age freeze–thaw cycles ... -
Post-peak behavior of concrete dams based on nonlinear finite element analyses
(Peer reviewed; Journal article, 2021)Dam failures are catastrophic events and in order to improve safety, engineers must have good tools for analysis and an understanding of the failure process. Since there are few cases of real failures in concrete dams, ... -
Ice load measurements on Rätan concrete dam using different sensor types
(Peer reviewed; Journal article, 2021)Concrete dams in cold regions are designed to withstand loads from the ice sheet on top of the reservoir.However, the ice load's magnitude and return period are among the most considerable uncertainties in safety assessments ... -
Influence of concrete’s mechanical properties on the cracking of concrete dams
(Chapter, 2021)Analytical methods of structural stability assessment of concrete dams are often too simple and thus conservative in their predictions.Without the actual foundation geometry, capacity for some rigid body failure modes are ... -
A Comprehensive Summary of Available Legislation and Practices in Demolition and Construction & Demolition Waste Management in the Arctic Region
(Peer reviewed; Journal article, 2021)The need for better natural resource use is currently increasingly recognised, and high emphasis is given to the circularity of building materials and the reduction of activities with negative environmental impact. ... -
Mechanical and durability properties of concrete subjected to early-age freeze–thaw cycles
(Peer reviewed; Journal article, 2021)Early-age frost damage to concrete used in winter construction or in cold environments negatively affects the development of the hydration process and the performance of the concrete, thereby reducing the service life of ... -
Low-temperature (-10 °C) curing of Portland cement paste – synergetic effects of 1 chloride-free antifreeze admixture C-S-H seeds, and room-temperature pre-curing
(Peer reviewed; Journal article, 2021)Cold weather drastically shortens the construction season in northern regions. Low ambient temperatures are known to have detrimental impacts on the reactivity and hardened performance of cementitious materials. This study ... -
Microbial Community Dynamics during Biodegradation of Crude Oil and Its Response to Biostimulation in Svalbard Seawater at Low Temperature
(Peer reviewed; Journal article, 2021)The development of oil exploration activities and an increase in shipping in Arctic areas have increased the risk of oil spills in this cold marine environment. The objective of this experimental study was to assess the ... -

(Peer reviewed; Journal article, 2021)The need for better natural resource use is currently increasingly recognised, and high emphasis is given to the circularity of building materials and the reduction of activities with negative environmental impact. ... -
Assessment of Hydrocarbon Degradation Potential in Microbial Communities in Arctic Sea Ice
(Peer reviewed; Journal article, 2022)The anthropogenic release of oil hydrocarbons into the cold marine environment is an increasing concern due to the elevated usage of sea routes and the exploration of new oil drilling sites in Arctic areas. The aim of this ... -
Ice conditions in northern Norwegian fjords: Observations and measurements from three winter seasons, 2017–2020
(Peer reviewed; Journal article, 2022)Freshwater provided by rivers beginning deep within the mountains, feeds into fjords along the coast of Norway, often forming a brackish surface layer that will change in its salinity, thickness, and extent throughout the ... -
Asset Management of Existing Concrete Bridges Using Digital Twins and BIM: a State-of-the-Art Literature Review
(Peer reviewed; Journal article, 2022)The need to optimize investments in bridge maintenance has created a demand for improved bridge management systems (BMS). Outdated practices in bridge inspection and constant advances in information technology have also ... -

(Peer reviewed; Journal article, 2022)Freshwater provided by rivers beginning deep within the mountains, feeds into fjords along the coast of Norway, often forming a brackish surface layer that will change in its salinity, thickness, and extent throughout the ... -
Large-scale shear test of brash ice
(Peer reviewed; Journal article, 2022)A large-scale shear apparatus has been originally developed and built to test the mechanical properties of coarsegrained material. It was used to evaluate the shear behaviour of brash ice. The brash ice blocks were collected ... -
Hvordan håndteres avrenning fra ferskfisktransport i andre fiskenasjoner, en komparativ studie av Irland, Island og Færøyene
(Nofima rapportserie, Research report, 2022)Det ble gjennomført en komparativ studie hos villfiskforedlere, lakseslakteri, transportbyrå og tilsynsmyndigheter i Irland, Island og Færøyene der man diskuterte problemstillingen rundt avrenning fra lastebiler som ... -
Corrosion-free concrete structures by the use of FRP (Fibre reinforced Polymers)
(Chapter, 2022)Fibre reinforced polymers may be suggested as a solution to one of the major durability problems with reinforced concrete; the corrosion of the internal steel reinforcement. The durability of fibre reinforced polymers, ... -
Redusere avrenning fra ferskfisk transport på lastebiler
(Lecture, 2022)By law, fresh fish is transported on ice in the EEA. This system is tried and proven and works perfectly except that upward of 1000 L of meltwater drain onto the road from a typical trailer load. This is most noticeable ... -
Wireless monitoring for assessment of concrete railway bridges - Experiences from field tests
(Chapter, 2022)This paper focus on assessment on a prestressed three span concrete box bridge by the use of a wireless monitoring system in combination with visual inspection. The bridge is located in the very north of Sweden, in Abisko. ... -
Non-destructive testing of prestressed concrete bridges - Experiments from field test
(Chapter, 2022)Most of the structures in the transport infrastructure are built of reinforced concrete, and many of our large bridges are built of prestressed concrete. A large part of these were built before 1980, and could theoretically ... -
Remote bridge inspection using optical methods
(Chapter, 2022)Routine bridge inspections usually consist of visual observations. These inspections are time-consuming and subjective. There is a need to identify new inspection techniques for infrastructure that reduce traffic disturbance, ...
