1. Recycling of concrete in new structural concrete
Sammanfattning : Concrete waste as crushed concrete aggregates (CCA) in structural concrete gives a new purpose and prolongs the technical life of the reference concrete accomplishing closed loop recycling. This research investigates CCA as aggregate replacement in an industrial reference concrete recipe as fine aggregate fractions and overall aggregate replacement. LÄS MER
2. Circularity in Thermal Recycling for Sustainable Carbon Fibers
Sammanfattning : The research field of composite materials is particularly fascinating due to the design freedom they offer and the infinite number of constituent combinations, including those that are already explored, and many more that are yet to be tried. One composite material that holds great potential contains carbon in its fiber shape. LÄS MER
3. Life cycle primary energy use and carbon emission of residential buildings
Sammanfattning : In this thesis, the primary energy use and carbon emissions of residential buildings are studied using a system analysis methodology with a life cycle perspective. The analysis includes production, operation, retrofitting and end-of-life phases and encompasses the entire natural resource chain. LÄS MER
4. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions
Sammanfattning : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. LÄS MER
5. Life cycle assessment of bridges, model development and case studies
Sammanfattning : In recent decades, the environmental issues from the construction sector have attracted increasing attention from both the public and authorities. Notably, the bridge construction is responsible for considerable amount of energy and raw material consumptions. LÄS MER
