  1. 11. Simulation of Hardening of the MahanaKhon Tower Mat Foundation

    University essay from KTH/Betongbyggnad

    Author : Zakaria Kazi-tani; [2019]
    Keywords : Hydration; MahanaKhon tower; mat foundation; young concrete; temperature development; thermal stresses; cracking; fly ash; finite element analysis; COMSOL Multiphysics; Hydratation; MahanaKhon tower; bottenplatta; ung betong; temperaturutveckling; termiska spänningar; sprickbildning; flygaska; finita elementanalys; COMSOL Multiphysics;

    Abstract : Cement hydration is the result of a series of simultaneous chemical reactions occurring during the production of concrete. An excessive amount of heat is generated, which consequently may give rise to thermal stresses and cause early age cracks in concrete that may affect its structural integrity, and load bearing capacity.

  3. 12. Alternative methods to prevent thermal cracking in concrete

    University essay from

    Author : Alexander Barchin; Navid Sedighi; [2019]
    Keywords : Massive concrete structures; heat development; cement hydration; temperature reduction; cracking; fly ash; ice; coarse aggregates; cooling methods; practical tests.; Massiva betongkonstruktioner; värmeutveckling; cementhydrataion; temperaturreducering; sprickbildning; flygaska; is; grov ballast; kylningsmetoder praktiska försök.;

    Abstract : In the construction industry, concrete is the most common material, because of its good properties such as compressive strength and endurance. Concrete is a composition of several different materials where one of the main components is cement. When the hydration process starts, large amount of heat is generated. READ MORE

  4. 13. Crack propagation calculations in non-elastic metals

    University essay from Luleå tekniska universitet/Material- och solidmekanik

    Author : Máren Ingá Baer; [2018]
    Keywords : crack propagation; fracture mechanics;

    Abstract : It is important to know the lifespan of a component, thus services can be planed. At Siemens Industrial Turbomachinery AB (SIT AB) develop and produce gas and steam turbines, the turbines are heavily strained by thermal and centrifugal forces during their life span which lead to cracking.

  5. 14. Potential of chemical recyclingto improve the recycling of plastic waste

    University essay from KTH/Energi och klimatstudier, ECS

    Author : Martyna Solis; [2018]
    Keywords : recycling; chemical recycling; plastic waste; plastic packaging; recycling rates; circular economy; Sweden; Stockholm; Stockholm Exergi; återvinning; kemisk återvinning; plastavfall; plastförpackning; återvinningsgrad; cirkulär ekonomi; Sverige; Stockholm; Stockholm Exergi;

    Abstract : Chemical recycling can improve the plastic recycling rates and reduce the level of CO2 from fossil plasticsproduction. Thus, it is seen as an attractive technology in the action towards meeting the emission, circulareconomy and recycling targets. In the Swedish context, it could help reach the carbon neutrality goal by2045. READ MORE

  6. 15. Failure analysis of suspension plasma sprayed thermal barrier coatings

    University essay from Högskolan Väst/Forskningsmiljön produktionsteknik(PTW)

    Author : Mohammed Jasim; [2017]
    Keywords : Failure analysis; Suspension plasma sprayed; Thermal barrier coating;

    Abstract : Thermal barrier coatings (TBC) are proven to protect the hot section of components operated under elevated temperature. Suspension Plasma Spray (SPS) is an emerging manufacturing process that is used to produce TBCsI, It has the ability to deposit a thinner TBC that has finer microstructure than coatings deposited using traditional Atmospheric Plasma Spray (APS).
