  1. 1. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast

    University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

    Author : Anna Hagberg; Andreas Andersson; [2023]
    Keywords : Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

    Abstract : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. READ MORE

  3. 2. Mouthfeel Assessment of Tetra Pak Paper Straws: Exploring the Correlation between Instrumental Measurements and Sensory Evaluation

    University essay from Lunds universitet/Förpackningslogistik

    Author : Natchaya Hanprerakriengkrai; [2023]
    Keywords : mouthfeel; paper straws; correlations; instrumental measurement; sensory evaluation; Technology and Engineering;

    Abstract : The implementation of the Single-Use Plastics Directive has gained significant attention due to the detrimental impacts of plastic pollution, leading to the transition from plastic straws to paper straws for Tetra Pak’s portion-size carton packages. However, the acceptance of paper straws could be hindered by negative mouthfeel perceptions, which customers find the difficulties to accurately describe them. READ MORE

  4. 3. 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 : Shotcrete; Global Warming Potential; Environmental Product Declaration; Tunnel construction; Fibre reinforcement; Compressive strength; Residual strength; GGBS; Sprutbetong; Klimatpåverkan; Miljövarudeklaration; Tunnelbyggande; Fiberarmering; Tryckhållfasthet; Residualhållfasthet; Granulerad Masugnsslagg;

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

  5. 4. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  6. 5. Optimization of a one-part geopolymerization method for lab-scale, using waste glass wool as a precursor

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Oscar Enander; [2022]
    Keywords : Materials chemistry; Geopolymer; Glass wool; Recycling; Curing time; Curing temperature; Cement; Chemistry;

    Abstract : Geopolymers are amorphous inorganic polymeric structures. They are used as binding agents and can be compared to cementitious materials such as ordinary Portland cement. This thesis aims to produce geopolymers from waste glass wool. Today glass wool is found in isolation, both thermal and sound insulation, and it is not being recycled. READ MORE
