  1. 16. Investigating Adoption of Digital Technologies in Construction Projects

    Författare :Yashar Gholami; Martin Rudberg; Micael Thunberg; Scott Fowler; Fredrik Tiedemann; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Technology Adoption; Digitalization; Main Contractors; Construction Projects; Construction Logistics; Innovation; Digital teknik; Byggentreprenörer; Byggprojekt; Bygglogistik; Innovation;

    Sammanfattning : This thesis investigates the adoption of digital technologies to improve logistics processes in construction projects. The focus is on the main contractor firms and construction projects, but first-tier suppliers, transportation firms, and technology vendors are also considered. LÄS MER

  3. 17. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport

    Författare :Liming Huang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Formation factor; Electrical conductivity; Moisture transport; Pore structure; Sustainable cement-based materials; Hydration; Alkali salts; Supplementary cementitious materials;

    Sammanfattning : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. LÄS MER

  4. 18. Decarbonization of construction supply chains - Achieving net-zero carbon emissions in the supply chains linked to the construction of buildings and transport infrastructure

    Författare :Ida Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Embodied carbon; Buildings; Emissions reduction; Transport infrastructure; Scenario analysis; Low carbon technology; Carbon abatement; Decarbonization; Construction; Supply chain; Carbon mitigation;

    Sammanfattning : Sweden has committed to reducing greenhouse gas (GHG) emissions to a net-zero level by Year 2045. In Sweden, about 20% of its annual CO2 emissions are from the manufacture, transport and processing of materials for both the construction and refurbishment of buildings and transport infrastructure.

    Sammanfattning : The design freedom Additive Manufacturing (AM) offers provides new solutions for improving functionality in industrial applications. It also offers unique opportunities when it comes to materials design. LÄS MER

  7. 20. Structure and properties of thick plate and near surface properties after high speed machining af AA7010

    Författare :Nils-Eric Andersson; Marcel A. J. Somers; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP; Construction materials;

    Sammanfattning : Using thick plates instead of forgings in the aircraft industry for integral construction of load carrying components is becoming more and more practice. The reasons are shorter lead-times from design of a modified or totally new component to introduction in an aircraft and smaller variations in properties for plate compared to forging. LÄS MER
