  1. 1. Laboratory testing of shotcrete with fibres of steel, basalt or synthetic materials

    Master-uppsats, KTH/Betongbyggnad

    Författare :Muralidharan Rengarajan; [2020]
    Nyckelord :Fibre reinforced shotcrete; Energy absorption; Residual strength; Fibres; and Laboratory testing;

    Sammanfattning : Shotcrete or sprayed concrete has become an inevitable material for stabilising and supporting hard rock tunnels. To prevent rock block fallouts in the excavated tunnel, shotcrete is pneumatically projected under high pressure on the rock surface. LÄS MER

  3. 2. Sjöofficershatt och dess hattask En föremålsstudie

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Alex Bernérus; [2019-06-19]
    Nyckelord :hat; costume accessory; textile; wood; uniform;

    Sammanfattning : The purpose of this study is to investigate and analyse a hat and its hat box, originally belonging to an officer of the Swedish marine during the late 19th century. The hat is constructed of different materials such as cotton, silk, gold threads, gold-plated buttons and wires, and leather. LÄS MER

  4. 3. Life cycle assessment comparison of CIPP lining and traditional pipe replacement

    Master-uppsats, KTH/Miljöstrategisk analys (fms)

    Författare :Daniel Berglund; [2015]
    Nyckelord :Relining; CIPP lining; traditional pipe replacement; comparative; LCA; life cycle assessment; housing industry; sewage pipe renovation; sewage pipe replacement; environment;

    Sammanfattning : During the so-called “Miljonprogrammet”, over a million homes were built in Stockholm. As the buildings mature, parts of the buildings reach their technical life times and it is time to renovate them. LÄS MER

  5. 4. Exposure studies of refractory materials for biomass gasification

    Master-uppsats, Institutionen för tillämpad fysik och elektronik

    Författare :Markus Carlborg; [2013]
    Nyckelord :Gasification; biomass; high alumina refractories; alkali; slag;

    Sammanfattning : Gasification is a technology mostly used to convert fossil feedstock to syngas. Biomass could be used as a feedstock instead but that puts different demands on, among other things, the materials in these reactors. LÄS MER

  7. 5. Tribological Performance of PTFE Composites at Breakaway in Sliding Lubricated Contacts

    Master-uppsats,

    Författare :Arash Golchin; [2011]
    Nyckelord :Technology; PTFE; Babbitt; breakaway; Teknik;

    Sammanfattning : Babbitt has long been used as the lining material in hydrodynamic sliding bearings. However, with the new operating conditions imposed on hydro-electric power plants due to grid frequency regulation, the power plants undergo more frequent starts and stops which increases the need for an alternative material with better friction characteristics at start-up compared to conventionally used white-metal (Babbitt).
