    Master-uppsats, Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Hannes Tornerefelt; Richard Wong; [2021]
    Nyckelord :concrete; CO2-emissions; cement; environment; material; construction; betong; koldioxidutsläpp; miljö; konstruktion; Technology and Engineering;

    Sammanfattning : The greenhouse effect and the emission of greenhouse gases, namely carbon dioxide, is a global issue which today permeates alot of the societal consciousness and therefore also alot of the conducted research. The construction industry is not different in this regard. LÄS MER

  3. 2. Dynamic analyses of hollow core slabs : Experimental and numerical analyses of an existing floor

    Master-uppsats, KTH/Bro- och stålbyggnad

    Sammanfattning : For intermediate floors in residential and office buildings, as well as in parking garages and malls, there is a wide use of hollow core concrete slabs in Sweden today. Hollow core slabs are precast and prestressed concrete elements with cylindrical-shaped voids extending along the length of the slab. LÄS MER

    Sammanfattning : I mars 2015 nådde den globalt genomsnittliga koldioxidhalten 400 ppm för första gången på tre miljoner år. Därför satte den svenska regeringen, år 2017, upp målet att Sverige ska vara klimatneutralt år 2045. LÄS MER

  5. 4. Cracking in a slender concrete slab due to thermal variation

    Master-uppsats, KTH/Betongbyggnad

    Författare :Johan Mattsson; Fredrik Åman; [2019]
    Nyckelord :Concrete slab; Concrete; Finite element analysis; Cracking; Thermal variation; Seasonal temperature; Abaqus; Brigade Plus; Betonggrund; Betong; Finit element analys; Sprickbildning; Termiska laster; Omgivningstemperature; Abaqus; Brigade Plus;

    Sammanfattning : Concrete slabs used in thepulp and paper industries are often situated outdoors, which means that theslabs are exposed to temperature variations due to different weatherconditions. These temperature variations together with operational temperaturesassociated with the manufacturing process, may introduce high temperaturegradients in the concrete. LÄS MER

  7. 5. Grävpålar - Dimensionering, utförande och användningsområden

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)
