  1. 1. Hydrophobic Impregnation of Concrete Structures Effects on Concrete Properties

    Detta är en avhandling från Stockholm : KTH

    Författare :Anders Selander; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrophobic impregnation; silane; siloxane; concrete; surface treatment; water repellent agent; building protection; impregnering; betong; silan; siloxan; ytbehandling; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Hydrophobic impregnations often referred to as water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. LÄS MER

  3. 3. Upgrading concrete bridges post-tensioning for higher loads

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jonny Nilimaa; Luleå tekniska universitet.; [2013]
    Nyckelord :Civil engineering and architecture - Building engineering; Concrete; Bridges; Upgrading; Strengthening; Shear; Field testing; Post-tensioning; Prestressing; Samhällsbyggnadsteknik och arkitektur - Byggnadsteknik; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : There are a great number of old structures around the world, some of which were designed for completely different purposes than in their current application. Swedish railway bridges were for example only designed for maximum axle loads of 200 kN in the beginning of the 20th century, while the highest axle loads of today are twice as high. LÄS MER

  4. 4. Concrete Fashion: Dress, Art, and Engagement in Public Space

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Kajsa G. Eriksson; Högskolan i Borås.; Göteborgs universitet.; University of Gothenburg.; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; fashion design; contemporary art; dressed body; artistic research; public space; identity; performance; Estetiska ämnen; Aesthetic subjects; documentation; engagement;

    Sammanfattning : This dissertation is an example of artistic research that explores the border between fashion design and contemporary art, in order to place situated bodily practices within the larger field of explor... meration and ideology, and to discover new formats. LÄS MER

  5. 5. Hardening concrete measurments and evaluation of non-elastic deformation and associated restraint stresses

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Hans Hedlund; Luleå tekniska universitet.; [2000]
    Nyckelord :Structural Engineering; Konstruktionsteknik;

    Sammanfattning : If a structural member of hardening concrete is restrained to some degree against expansion and contraction during the heating phase of the hydration process and the subsequent contraction phase, stresses will be induced. The issue of primary interest is whether or not these induced stresses will lead to cracking. LÄS MER
