  1. 1. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders

    Författare :Mirja Rothhämel; Jan Laue; Sven Knutsson; Craig Lake; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft soil; clay; silt; silty sand; soil stabilisation; hydraulic binder; cement; lime; by-product; cement kiln dust CKD ; cold climate; frost; freeze-thaw; laboratory test; field test; subsoil; road construction; feinkörninge Böden; Ton; Schluff; schluffiger Sand; Bodenstabilisierung; hydraulische Bindemittel; Zement; Kalk; Nebenprodukt; Zementofenstaub; kaltes Klima; Frost; Frost-Tau; Laborversuche; Feldversuche; Verkehrsbau; Dauerhaftigkeit; finkornig jord; lera; silt; siltig sand; jordstabilisering; hydraulisk bindemedel; cement; kalk; biprodukt; cement kiln dust CKD ; kallt klimat; frost; frysning-tining; laboratorieanalyser; fältförsök; vägterrass; Geoteknik; Soil Mechanics;

    Sammanfattning : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER

  2. 2. Grouting of Hard Rock with Gelling Liquids, Field and Laboratory Studies of Silica sol

    Författare :Johan Funehag; Chalmers University of Technology; []
    Nyckelord :aperture; penetration length; gelling liquids; field study; silica sol; colloidal silica; Grouting; propagation; hydraulic test; sand column; rheology; transmissivity;

    Sammanfattning : Recent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is a cement-based one. During the past 10 years, the acceptable flow of water into tunnels has been significantly reduced. The current requirements mean that an average fracture aperture of around 0. LÄS MER

  3. 3. Hydraulic Conductivity of Saturated Sand-Bentonite mixtures

    Författare :Malin Sundsten; Chalmers University of Technology; []
    Nyckelord :quarry sand; design; bentonite; landfill barrier; field tests; dry density; foundry green sand; laboratory tests; hydraulic conductivity;

    Sammanfattning : The implementation of the EC directive concerning landfill liners and covers sets stricter technical and environmental requirements for landfill barriers. It is therefore essential to identify suitable materials that fulfil these requirements. LÄS MER

  4. 4. Thermal response test : method development and evaluation

    Författare :Signhild Gehlin; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

  5. 5. Numerical and experimental study of performance of a hydraulic motor

    Författare :Leon Dahlén; Mittuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Hydraulic fluid; hydrostatic transmission; hydraulic motor; Engineering mechanics; Teknisk mekanik; Maskinelement; Machine Elements;

    Sammanfattning : The aim of this study was to develop an understanding of the fluid properties that influence the efficiency of hydraulic systems in a steady-state, especially components in hydrostatic transmission systems under different running conditions. The aim has also been to investigate and model the sources of losses in hydraulic machines, in order to estimate the losses, taking fluid properties into account. LÄS MER
