  1. 1. Praktisk tillämpning av klimatförbättrad betong : Litteraturstudie, observationsstudie och dokumentanalys

    Master-uppsats, KTH/Betongbyggnad

    Författare :Alina Mansour; [2022]
    Nyckelord :;

    Sammanfattning : Due to its good properties such as high strength, formability and durability concrete is one of the world's most widely used materials. At the same time, concrete, or rather the production of the concrete's main raw material, cement, has a negative climate impact. This is because a lot of carbon dioxide is emitted during the manufacturing process. LÄS MER

    Sammanfattning : Självtorkande betong behöver en hög halt cement för att fungera väl, vilket direkt leder till begränsande möjligheter till reduktion av koldioxidutsläpp. Intresset för att finna alternativ till en hög cementhalt är därför stort. LÄS MER

  4. 3. Environmental and technical evaluation of cement reduction and test methods for fibre reinforced shotcrete in tunnels

    Master-uppsats, KTH/Betongbyggnad

    Författare :Elin Brodd; Lina Östlund; [2022]
    Nyckelord :Shotcrete; Global Warming Potential; Environmental Product Declaration; Tunnel construction; Fibre reinforcement; Compressive strength; Residual strength; GGBS; Sprutbetong; Klimatpåverkan; Miljövarudeklaration; Tunnelbyggande; Fiberarmering; Tryckhållfasthet; Residualhållfasthet; Granulerad Masugnsslagg;

    Sammanfattning : The dominating support method for hard rock tunnels today is use of fibre reinforced shotcrete in combination with rock bolts. The fibre reinforced shotcrete secures smaller blocks, while rock bolts are used to support larger blocks in the rock. Application of shotcrete is done by spraying against the rock surface using compressed air. LÄS MER

    Sammanfattning : In 2017, the Swedish Parliament stated a new climate law with the goal that Sweden should be climate neutral by 2045. The concrete industry has developed a roadmap on how the goal for 2045 can be achieved, where one way to reduce the carbon emissions from concrete is by replacing a part of the cement clinker with alternative binders in the concrete mix.
