  1. 1. Environmental Perspectives on Urban Material Stocks used in Construction : Granular Materials

    Författare :Simon Magnusson; Sven Knutsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The peoples demand of functions and services in cities is the driver for energy and material flows. Most people in the world are now living in urban areas. In order to achieve a sustainable development of cities, both resource use and environmental impact have to be reduced. LÄS MER

  3. 2. Decarbonising the Stainless Steelmaking through Alloy Solutions

    Författare :Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. LÄS MER

  4. 3. Material Flows Incurred by Activities at Project Sites

    Författare :Nina Modig; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temporary organization; project site; project; supply network; logistics; material flows;

    Sammanfattning : The execution of numerous projects is dependent on the movement of large quantities of heterogeneous material to and from project sites. This has to be done in a timely manner to successfully produce desired outputs, e.g. buildings, concerts, peacekeeping operations and sport events. LÄS MER

  5. 4. Material metabolism of residential buildings in Sweden: Material intensity database, stocks and flows, and spatial analysis

    Författare :Paul Gontia; Chalmers tekniska högskola; []

    Sammanfattning : Construction materials are used for the expansion and maintenance of the built environment. In the last century, construction material stock has increased globally 23-fold. LÄS MER

  7. 5. A Study on Particle Motion and Deposition Rate : Application in Steel Flows

    Författare :Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Stein Tore Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

    Sammanfattning : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. LÄS MER
