  2. 11. Aspects of probabalistic serviceability limit state design of dry deep mixing

    Author : Niclas Bergman; Stefan Larsson; Tim Länsivaara; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : An expanding population and increased need for infrastructure increasingly necessitate construction on surfaces with poor soil conditions. To facilitate the construction of buildings, roads and railroads in areas with poor soil conditions, these areas are often improved by means of foundation engineering. READ MORE

  4. 12. Stabilization-solidification of high water content dredged sediment : Strength, compressibility and durability evaluations

    Author : Gregory Makusa; Kauko Kujala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. READ MORE

  5. 13. Computational Railway Dynamics - Integrated Train - Track - Subgrade Modeling and Simulations

    Author : Håkan Lane; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The primary objective of the thesis has been to extend the capabilities for computational modeling, prediction and simulation of the elastic response of the train, track structure and soil in railway systems. The industrial background is the high level of ground borne vibrations reported from citizens as a consequence of train traffic (in particular from high speed trains) in several Swedish locations.

  6. 14. Shrinkage and Related Properties of Alkali-Activated Binders Based on High MgO Blast Furnace Slag

    Author : Abeer Humad; Andrzej Cwirzen; John L. Provis; Karin Habermehl-Cwirzen; Andrzej Garbacz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali-activated slag; alkali-activated materials; high-MgO blast furnace slag; shrinkage; creep; carbonation; strength; heat curing; Byggmaterial; Building Materials;

    Abstract : Concrete is the second most used material in the world just after water. A drawback is that it is mostly based on Portland cement, which has an extremely high carbon footprint reaching a staggering 900 kg/tonne. The carbon dioxide emissions related to the production of the Portland cement accounts for nearly 8 % of the global total. READ MORE

  7. 15. Comparative Study of Chemical Additives Effects on Dry Grinding Performance

    Author : Vitalis Chipakwe; Saeed Chehreh Chelgani; Jan Rosenkranz; Tommy Karlkvist; Kirsten Claire Corin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Energy; Grinding aid; Flowability; Dry grinding; FT4 Powder Rheometer; Surface properties; Mineral Processing; Mineralteknik;

    Abstract : The application of chemical additives, known as grinding aids (GA), dates back to 1930 in the cement industry. As opposed to the cement industry, where the use of GAs is on the final processing step, it could be one of the first process steps in ore beneficiation. READ MORE
