  1. 11. Environmental and technical evaluation of cement reduction and test methods for fibre reinforced shotcrete in tunnels

    University essay from KTH/Betongbyggnad

    Author : Elin Brodd; Lina Östlund; [2022]
    Keywords : ;

    Abstract : The dominating support method for hard rock tunnels today is use of fibre reinforcedshotcrete in combination with rock bolts. The fibre reinforced shotcretesecures smaller blocks, while rock bolts are used to support larger blocks in therock. Application of shotcrete is done by spraying against the rock surface usingcompressed air. READ MORE

  3. 12. Metallurgical analysis of some osmund iron from Sweden and Estonia : A short historical review of medieval iron production and export

    University essay from KTH/Materialvetenskap

    Author : Ellinor Fischbein; Felicia Larsson; [2021]
    Keywords : ;

    Abstract : During the Middle Ages, Sweden was a coveted exporter of high-quality iron in Europe. Bloomery furnaces could have produced osmund iron. However, most osmund iron was produced in blast furnaces. The iron was then treated in the finery process and cut into pieces. READ MORE

  4. 13. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Anton Sundström; [2020]
    Keywords : DEM; Discrete element method;

    Abstract : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. READ MORE
