  1. 1. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast

    University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

    Author : Anna Hagberg; Andreas Andersson; [2023]
    Keywords : Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

    Abstract : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. READ MORE

  3. 2. Conditions for Industrial Symbiosis surrounding a hydrogen based steel industry

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

    Author : Erland Nylund; [2023]
    Keywords : Industrial Symbiosis; H-DRI steelmaking; Industrial Symbiosis Networks; Waste management; Supplementary Cementitious Material SCM ; circular economy; Industriell symbios; H-DRI stålproduktion; Industriell Symbios-nätverk; restmaterialhantering; alternativa cementmaterial; SCM ; cirkulär ekonomi.;

    Abstract : There is an ongoing transition to a more sustainable industry with lower climate impact. As part of this transition, the steel industry is expected to move from the conventional process for producing iron and steel using Blast Furnace (BF) and Basic Oxygen Furnace (BOF) processes, consuming large amounts of fossil fuels.

  4. 3. How circular business models can increase the use of 3R’s - a shift towards circular economy : Case study in Swedish stone material industry

    University essay from Karlstads universitet/Handelshögskolan (from 2013)

    Author : Elsa Pedersen; Alva Eriksson; [2022]
    Keywords : 3R reduce; reuse; recycling ; business model innovation; circular business model; circular economy; stone material; strategy; strategical transformation; regulations; 3R återvinning; återanvändning; reducering ; affärsmodellsinnovation; cirkulär affärsmodell; cirkulär ekonomi; stenmaterial; strategi; strategisk förändring; regleringar;

    Abstract : Circular economy (CE) is today gaining a lot of attention, which means to improve resource efficiency through reusing, recycling, and reducing (3R). Increased CE is one step towards improved sustainable development. The aim in this study is to explain how circular economy can pursue sustainable development, by business model innovation.

  5. 4. An Overview of State-of-the-art Hydraulic Conductivity Measurements in Coarse Grained Materials

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jakob Andrén; [2021]
    Keywords : hydraulic conductivity; permeability; embankment dam; coarse grained; flow regime; hydraulisk konduktivitetsmätning; permeabilitet; fyllnadsdamm; grovkorniga material; flödesregim;

    Abstract : Embankment dams are made from soil materials of varying sizes and widely used all over the world.When constructing these, knowing the hydraulic conductivity (K) of the soil materials is a keyparameter in order to construct safe embankment dams. A knowledge gap regarding K measurementsin coarse grained soils has been identified. READ MORE

  6. 5. Determination of thermal conductivity for mastic asphalt by combining previously performed laboratory work and TASEF

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Martin Kruse Lindgren; [2021]
    Keywords : Mastic asphalt; BPGJA-11; thermal conductivity; TASEF; FEM; Timber; Gjutasfalt; BPGJA-11; termisk konduktivitet; TASEF; FEM; Trä;

    Abstract : Mastic asphalt is a material which in Sweden mainly is used as coating for bridges, parking decks, courtyards and terraces. Mastic asphalt is a material built-up by a combination of bitumen (a type of binder), well-graded aggregate (consists of both coarse and fine ballast), filler, sand and sometimes also fine graded macadam.
