11. Concrete with low carbon dioxid emissions : Reduced amount of cement with husk ashes
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : The world is facing a major climate threat where carbon dioxide emissions are in focus. At the same time, society requires new buildings and developed infrastructure. Concrete is one of the most common building materials and 30 billion tonnes are produced annually, which corresponds to about 6 percent of the world's carbon dioxide emissions. LÄS MER
12. Burning material behaviour in hypoxic environments: An experimental study examining fire dynamics of composite materials in vitiated conditions
Master-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : The progression of fire safety research has contributed to improving the guiding principles of standardised building design. Research making use of pure materials, once common in homes and workplaces, are less relevant as such materials are no longer as prevalent. LÄS MER
13. Att skydda det skyddade : korttidseffekter av hägn på trädföryngring i tre skånska skogsreservat
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Biotiska och abiotiska faktorer har stor inverkan på vilka arter som växer i skogen. Graden av inverkan kan bero på betesskador från klövvilt och tillgång på ljus. Betesskador och ljustillgång kan dels reglera nivån på föryngringen, dels på fördelningen av trädslag i den tempererade skogen. LÄS MER
14. Utveckling av marknader för avfallsbaserade resurser : En fallstudie på återanvändning av komplexa avfallsströmmar ur ett värdekedjeperspektiv
Master-uppsats, Linköpings universitet/Industriell miljöteknikSammanfattning : Immense amounts of waste are generated daily by our society, and the management of these streams is a critical societal function. Part of this work is reusing and recycling materials with attractive properties, which is also an imperative step towards circular material flows. LÄS MER
15. Alternative methods to prevent thermal cracking in concrete
M1-uppsats,Sammanfattning : In the construction industry, concrete is the most common material, because of its good properties such as compressive strength and endurance. Concrete is a composition of several different materials where one of the main components is cement. When the hydration process starts, large amount of heat is generated. LÄS MER
