  1. 1. Steel fibrous cement based composites: material and mechanical properties : behavior in the anchorage zones of prestressed bridges

    Author : Lutfi Ay; KTH; []
    Keywords : process improvement of bridges; prestressed concrete; high performance concrete;

    Abstract : This PhD thesis is divided into two parts. Part one dealswith the development of the material and the mechanicalproperties of Steel Fibrous Cement Based Composites (SFCBC) forimproving bridge design and construction. It familiarizes thehydration mechanisms of the high performance concrete with thehelp of Powers´ and Jensen´s models. READ MORE

  2. 2. Utilisation of chemically inert or puzzolanic particles to modify concrete properties and save cement

    Author : Helena Moosberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : As the industrial production of minerals and metals increases, the amount of wastes becomes an environmental problem that must be delt with. It is imperative for the future to that these materials are regarded as resources to be utilised in other industries. READ MORE

  3. 3. Mass Stabilization, Stability and Settlement in Mass Stabilized Peat

    Author : Nenad Jelisic; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mass stabilization; stabilizer; field investigations; laboratory investigations; settlement; stability; peat; Building construction; Byggnadsteknik;

    Abstract : Peat is badly suited as a base for road and railway embankments due to its geotechnical properties. The usual procedure has been, therefore, to excavate peat and replace it with blasted rock. READ MORE

  4. 4. Ultrasonic characterization of materials and multiphase flows

    Author : Johan Carlson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : This thesis deals with three different applications of ultrasound measurement technology. In process industries like the mining industry, the oil and gas industry, and the paper pulp industry, multiphase flows play an important role. READ MORE

  5. 5. The use of air pollution control residues in landfill covers and for soil stabilization

    Author : Igor Travar; Richard Beaven; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : About 66% of all heat energy generated in Sweden originates from the incineration of municipal solid waste and biofuels such as wood, cardboard and peat. In addition to heat energy, incinerators generate about 1.7 Mt of ashes each year, of which 500 000 t are air pollution control (APC) residues. READ MORE
