Understanding the freezing and thawing processes in porous media such as soils is important, especially in regions experiencing seasonal frost or permafrost. These processes have a wide range of implications as diverse as how to maintain the structural integrity of roads, railways, pipelines, and buildings, to when to plant seeds during the growth season. Thawing of frozen ground is the opposite ...

Formålet med denne oppgaven er å gjøre petrologiske og petrografiske undersøkelser av en mafisk linse på Sandøya i vest-Troms for å rekonstruere metamorfe trykk og temperaturforhold, samt å gjøre dateringer for å utrede alderen på metamorfosen(e). Linsa ligge blottlagt ved havet ved Mjølvika på Sandøya. Kjernen er tilnærmet udeformert og består av en en massiv granatførende bergart med en grønn ...

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 ...
