1. 16. Kartläggning av vad som krävs för att svenska byggföretag ska övergå till miljöbetong : En enkätundersökning

   M1-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

   Författare :Moa Lindqvist; Lisa Lindqvist Berglund; [2020]
   Nyckelord :concrete; environment; green concrete; survey; indisposed to change; building companies; building material; environmental concrete; material; portland cement; betong; miljö; grön betong; enkätundersökning; förändringsobenägen; byggbransch; byggföretag; byggnadsmaterial; miljöbetong; material; materialval; portlandcement; betongval;

   Sammanfattning : Today Portland cement based concrete is used in great extent in building construction, which is an environmental problem as cement production stands for 5-8 % of total global greenhouse gases.  A need for a more environmentally friendly concrete is growing. LÄS MER

3. 17. An investigation of some properties of Shredder Fines and an element analysis of its ash to find new ways of dealing with this waste

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Adeel Naidoo; [2020]
   Nyckelord :Shredder fines; Bottom ash; Ash analysis; Combustion; Chemical fractionation; Elemental analysis; Cement industry; Metal recovery;

   Sammanfattning : Shredder fines are the materials with a particle size of less than 10 mm resulting from the shredding of vehicles and complex metal scrap from industries and municipalities. This waste is currently used as landfill construction material, but Stena Recycling wanted to know whether the bottom ash from the combustion of this waste could be useful to the cement industry, and whether it would be feasible to extract Cu and Zn from this ash.

   Sammanfattning : This Thesis is about the aging of FECRAL surface coatings. In this thesis various substrates have been investigated such as 16 Mo3, 304, 347, Sanicro 31, 800HT, Nikrothal 80 and Kanthal APMT. LÄS MER

5. 19. High Temperature Tribology in Hot Stamping

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Evan Kurnia; [2019]
   Nyckelord :high temperature tribology; hot stamping; acoustic emission; condition monitoring; hardfacing;

   Sammanfattning : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. LÄS MER

7. 20. Influence of ventilation on ro-ro space fire development : A study using two-zone fire models in order to explore tendencies of how different ventilation parameters affects the fire development in a ro-ro space

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Martin Lindgren; Andreas Lilja; [2019]
   Nyckelord :Fire; Ro-ro space; Ventilation; Simulation; Two-zone model; Brand; Rorolastutrymme; Ventilation; Simulering; Tvåzonsmodell;

   Sammanfattning : A ship to which vehicles and other loads can be rolled on and off is usually named ro-ro ship. A ro-ro ship consists of large corridor shaped space, normally extending to a considerable length or the entire length of the ship, which is usually loaded with various vehicles or stowage units.
