  2. 1. Experimental studies of ion transport in cementitious materials under partially saturated conditions

    Author : Nilla Olsson; Avdelningen för Byggnadsmaterial; []
    Keywords : Cement; Bruk; Betong; Jontransport; Fukttransport; Sorptionsisoterm; Tillsatsmaterial; Kiselstoft; Masugnsslagg; Ciment; Mortier; Béton; Transport ionique; Transport d humidité; Sorption de vapeur d eau; Additions minérales; Fumée de silice; Laitier de haut fourneau granulé moulu; Cement; Mortar; Concrete; Ion transport; moisture transport; Water vapor sorption; Supplementary cementitious materials SCMs ; Silica fume; Ground granulated blast furnace slag;

    Abstract : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. READ MORE

  4. 2. Experimental Study of De-icing Salt-frost Scaling in Concrete with Low-calcium Fly Ash or Slag : Influence of Drying and Carbonation, and Air Content

    Author : Martin Strand; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Betong; Cement; Beständighet; Tösalt-frost avskalning; Tillsatsmaterial; Masugnsslagg; Flygaska; Concrete; Durability; De-icing salt-frost scaling; Cement based materials; Supplementary cementitious materials SCMs ; Ground granulated blast furnace slag; Low-calcium fly ash;

    Abstract : In order to reduce the net climate impact of concrete production, it is necessary for the industry to undertake several actions. Among these is to include fly ash and slag as supplementary cementitious materials. Accordingly, this project has studied concrete containing low-calcium fly ash or ground-granulated blast-furnace slag. READ MORE

  5. 3. Hydration, pore structure, and related moisture properties of fly ash blended cement-based materials : Experimental methods and laboratory measurements

    Author : Oskar Linderoth; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Murbruk; Betong; Hydratation; Porstruktur; Sorption; Fukttransport; Mineraliska tillsatsmaterial; Flygaska; Cement; Mortar; Concrete; Hydration; Pore structure; Water vapour sorption; Moisture transport; Supplementary cementitious materials; Fly ash;

    Abstract : Cement-based materials, such as mortar and concrete, are the most employed construction materials in the world. Cement is an important component; it reacts with water to form a glue, called cement paste, which causes the material to harden. Today, cement production accounts for a significant portion of the world’s annual carbon dioxide emissions. READ MORE

  6. 4. Towards more sustainable approaches for protecting surfaces against wear

    Author : Kaveh Torkashvand; Mohit Kumar Gupta; Nuria Espallargas; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; HVAF spraying; WC-Based Coatings; Sustainability; Binder Chemistry; Slitage; HVAF; WC-baserade beläggningar; Hållbar produktion; Bindemedelskemi; Production Technology; Produktionsteknik;

    Abstract : WC-Co coatings, with and without chromium additives, are widely used in the industry for severe tribological applications. However, concerns about cobalt supply and its environmental and health impacts have led industries to explore sustainable binder alternatives. READ MORE

  7. 5. Laser Welding and Additive Manufacturing of Duplex Stainless Steels : Properties and Microstructure Characterization

    Author : Amir Baghdadchi; Leif Karlsson; Vahid Hosseini; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Technology; Produktionsteknik;

    Abstract : Duplex stainless steels (DSS), with a ferritic-austenitic microstructure, are used ina wide range of applications thanks to their high corrosion resistance and excellent mechanical properties. However, efficient and successful production and joining of DSS require precise control of processes and an in-depth understanding o frelations between composition, processing thermal cycles, resulting microstructures and properties.
