  1. 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

    University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

    Author : Anna Hagberg; Andreas Andersson; [2023]
    Keywords : Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

    Abstract : 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. READ MORE

  4. 3. Vitality of Sycamore maple (Acer pseudoplatanus) in southwest Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Karin Pershagen; [2021]
    Keywords : invasive species; climate adaptation; tree vitality; epiphytes; sooty bark disease;

    Abstract : Non-native tree species provide alternatives for forestry that needs to adapt to climate change and multiple public demands. In Sweden, Sycamore maple (Acer pseudoplatanus) is a non-native tree species with potential, both in wood production and as a support to biodiversity in woodlands and in urban settings. READ MORE

  5. 4. Evaluation of air entraining behaviour in concrete using computer aided methods on hardened samples

    University essay from KTH/Betongbyggnad

    Author : Jakub Pawlowicz; [2019]
    Keywords : concrete; air voids; air entraining; AEA; blast furnace slag; BFS; flat-bed scanner; BubbleCounter; traverse method;

    Abstract : Increasing awareness of sustainability in the concrete industry forces structural design and executionto focus on avoiding costly and unpredictable maintenance action, instead paying higher attention todamage prevention by direct actions on early stages of production. One of such approaches, whichdeals with the problem of freezing and thawing deterioration, is intentional air bubble introductionto the concrete mix. READ MORE

  6. 5. Graphene as an aqueous Lubricant

    University essay from KTH/Maskinkonstruktion (Inst.)
