This study investigated the feasibility of producing low carbon concrete (LCC) using supplementary cementitious materials (SCMs) and evaluated their impact on concrete F-T durability. Variations in the curing conditions were done to see the effect it had on the F-T resistance. These results were then supported by compressive- and chloride migration testing. The performance of different concrete ...

Microbial fuel cells (MFC) are emerging technologies that can produce electricity while treating wastewater. A series of tests were carried out to evaluate the efficiency of this technology for treating dairy wastewater (DWW). The experiments used Shewanella baltica as an exoelectrogen in a small single MFC to treat simulated DWW. The impacts of various operational factors, specifically pH, ...

A The innovative idea of utilization of iron ore dust (IODust), characterized by red hue typical for Narvik, came up during designing artwork for The Arctic University of Norway campus Narvik. The use of waste from iron ore production as a natural pigment was completed by partial replacement of natural aggregates (NA) by recycled concrete aggregates (RCA) to achieve a higher level of material ...

Grunnet økningen i energipriser og økt press om å nå klimamål, har energiøkonomisering i bygg blitt et samfunnsaktuelt tema. Masteroppgaven bruker Vigør Rehabiliteringssykehus vannbårne varmeanlegg som et eksempelstudie, der formålet med oppgaven er å forenkle driften, redusere energiforbruket og kutte energikostnadene tilknyttet varmeanlegget. Siden 2000-tallet er et er gjort en rekke forsøk på å ...

The use of recycled concrete aggregate (RCA) is one way to reduce the depletion of raw materials for the production of concrete. In this article RCA was tested and evaluated. Concrete with 25 to 80 % of RCA was examined in terms of its durability performance, particularly capillary absorption and shrinkage. Capillary absorption testing showed that RCA has better or identical results as the reference ...

Alternative to traditional concrete, sustainable concrete reduces cement content, waste management issues, and CO2 emissions. To achieve sustainable concrete, waste materials can be used as supplementary cementitious materials (SCMs) to partially replace cement. Fly ash, ground-granulated blast furnace slag, and silica fume have been heavily studied as SCMs. However, due to the retirement of coal-fired ...

A discussion related to the selection of a proper design basis for Arctic infrastructure facilities is presented. The design basis, which must be sufficiently robust to ensure safe operations of the facilities during their planned lifetime, should include relevant information available from the local and indigenous people of the area. The need to properly document all data and assumptions made ...

Byggebransjen utvikles kontinuerlig, både med tanke på utførelse og verktøyene som benyttes på byggeplass men også hvordan selve prosjekteringsprosessen gjennomføres. Bruken av BIM i større prosjekter blir mer og mer vanlig, men potensialet som ligger i BIM som verktøy utnyttes i mange tilfeller svært lite effektivt. Det blir i mange prosjekter produsert både modell og tegninger for å sikre ...

Hjelpemidler og utstyr i byggebransjen er i stadig endring. Muligheten for å kunne gjennomføre byggtekniske inspeksjoner på en bedre måte er på god vei, nemlig ved bruk av droner. Droneinspeksjoner har blitt mer vanlig i de siste årene, da særlig på grunn av kostnadsbesparelse og innovasjon. Tema for denne oppgaven er byggteknisk droneinspeksjon, og hvilke fordeler og ulemper er det ved bruk av ...

Concrete is one of the most common building materials in the Northern Periphery and Arctic, and therefore we should pay attention to its quality while reducing its carbon footprint. The concrete industry has established many measures to limit greenhouse gas emissions from concrete, as stated in the environmental product declaration (EPD). The most significant contributor is cement (common dose ...
