1. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för ByggnadsmaterialSammanfattning : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. LÄS MER
2. Use of Polyvinyl chloride (PVC) as an aggregate for concrete
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : This study investigates the use of polyvinyl chloride (PVC) as a partial substitute of natural aggregates in concrete as fine and coarse aggregates. Concrete was prepared by replacing natural aggregates with equal volume of grinded PVC, with volume replacement ratio as 10%, 50% for fine and then 10% and 50% for coarse aggregates. LÄS MER
3. Utilization of Rubber and Plastic Waste as A Partial Replacement of Aggregate for Improved Sound Insulation
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Arkitektur och vattenSammanfattning : Globally, billions of tons of rubber and plastic waste are produced annually, and because these wastes degrade so slowly (about 450 years for plastic bottles and 80 years for tire rubbers), they are extremely difficult to dispose of. As a result, utilizing these wastes directly in building materials can significantly reduce the environmental load while also increasing the sustainability of the building material. LÄS MER
4. Determination of thermal conductivity for mastic asphalt by combining previously performed laboratory work and TASEF
Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brandSammanfattning : Mastic asphalt is a material which in Sweden mainly is used as coating for bridges, parking decks, courtyards and terraces. Mastic asphalt is a material built-up by a combination of bitumen (a type of binder), well-graded aggregate (consists of both coarse and fine ballast), filler, sand and sometimes also fine graded macadam.

5. Experimental Tests of Pre - placed Aggregate Concrete for Concrete Repairs
Master-uppsats, KTH/BetongbyggnadSammanfattning : Since a large part of the hydropower structures in Sweden was built in the 1950s and 1960s, many of them are slowly but surely exhibiting deterioration. The hydropower companies are facing big challenges and are consequently investing in effective repairing methods since a hydropower structure failure could pose serious consequences and dangers to people, the environment, and the community.
