  1. 1. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Johanna Bergström; [2023-09-15]
    Keywords : Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

    Abstract : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. READ MORE

  3. 2. Loading tests on composite concrete columns : A comparison between composite columns made of permanent 3DPC formwork filled with SCC and columns made of homogenous SCC

    University essay from KTH/Betongbyggnad

    Author : Abdulla Al-Bazarkan; Hussain Alahmad; [2023]
    Keywords : ;

    Abstract : In order to achieve increased sustainability when casting concrete structures this thesis investigates the possibility of utilizing 3D-printing to construct formwork and digitalize construction. By digitizing construction less workers are needed and therefore less capital. READ MORE

  4. 3. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Doris Dijak; Elin Torstensson; [2023]
