  1. 1. Integrated Life Cycle Design - Applied to concrete multi-dwelling buildings

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Mats Öberg; Lund University.; Lunds universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; livslängd; materialval; energianvändning; inomhusklimat; livscykelanalyser; livscykelkostnader; hållbar utveckling; Sustainable construction; Building construction; Service life design; Multiple Attribute Decision Analysis; Energy efficient buildings; Life Cycle Assessment; projektering; betongkonstruktioner; flerbostadshus; Byggnadsteknik; Integrated life cycle design; Life Cycle Costing;

    Abstract : The objective of this work is to explore ways of enhancing the overall lifetime quality, including cost and environmental efficiency, of Swedish concrete multi-dwelling buildings. The building and its characteristics, as well as the procedures for whole life optimisation, are addressed. READ MORE

  2. 2. Co-firing complex biomass in a CFB boiler ash transformation, corrosion control and materials selection

    University dissertation from Umeå : Umeå University

    Author : Henrik Hagman; Umeå universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ash transformation; process control; equilibrium calculations; boiler availability; failures; alloy selection; alloy degradation; vortex finder VF ; service life estimation; sulfation; chloridation; high temperature corrosion; biomass; waste derived fuels; forest residues; RDF; Biomal; slaughterhouse waste; peat; waste wood; industrial waste water treatment sludge; HAD; RSMT; Alloy 253MA; Alloy 310S; Alloy 800H HT; Alloy DS; Alloy 600;

    Abstract : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

  3. 3. Corrosion of steel in concrete

    University dissertation from Swedish Cement and Concrete Research Institute, Stockholm

    Author : Kyösti Tuutti; [1982]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; carbonation; chloride penetration; threshold values; free and bound chloride; acceptable depth of corrosion; corrosion products; environment types; cracks; cement type; service life calculations; test methods; korrosion; betong; betongkonstruktioner; armeringskorrosion; kloridinträngning; sprickor; livslängdsberäkningar;

    Abstract : The research work that is presented in this thesis aims at mapping out the various mechanisms which control the process of steel corrosion in concrete. The process of corrosion is illustrated with a schematic model where the service life is divided into a period of initiation and a period of propagation. READ MORE

  4. 4. Environmental Assessment of Building Products and Components in a Service Life Perspective

    University dissertation from Stockholm : Byggvetenskap

    Author : Åsa Rimsjö; KTH.; [2003]
    Keywords : ;

    Abstract : This thesis presents a survey of different tools, used byenvironmental consultants in Sweden, for their recommendationsof building products and components in different constructionprojects. The goal was to identify possible improvements of thetools so that life cycle methodology could be used to a largerextent than today. READ MORE

  5. 5. A NEW APPROACH TO CRACK CONTROL FOR REINFORCED CONCRETE - An investigation of crack widhts close to the reinforcement and the correlation to service life

    University dissertation from The Division of Structural Engineering

    Author : Kristian Tammo; Lund University.; Lunds universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete cover; corrosion; Crack width; steel stress and service life;

    Abstract : One of the most important factors governing durability of concrete structures is reinforcement corrosion, and to prevent degradation associated with it, it is desirable to use large concrete covers. However, if the concrete cover is increased, the majority of design methods will predict that the crack widths at the concrete surface increase significantly. READ MORE
