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

    University dissertation from Stockholm : KTH

    Author : Anders Selander; KTH.; [2010]
    Keywords : Engineering and Technology Civil Engineering; Teknik och teknologier Samhällsbyggnadsteknik; 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;

    Abstract : 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. READ MORE

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

    University dissertation from Luleå tekniska universitet

    Author : Hans Hedlund; Luleå University of Technology.; Luleå University of Technology.; Luleå University of Technology.; [2000]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 5. Concrete Structures Subjected to Blast and Fragment Impacts - Numerical Simulations of Reinforced and Fibre-reinforced Concrete

    University dissertation from Chalmers University of Technology

    Author : Ulrika Nyström; Chalmers tekniska högskola.; Chalmers University of Technology.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsteknik; Construction engineering; Concrete; weapon effects; blast wave; fragment impact; numerical simulations; fibre-reinforced concrete; reinforced concrete; SDOF;

    Abstract : Concrete is widely used in design of protective structures due to its good energy-absorbing characteristics under high pressures and, when properly reinforced, ductile behaviour. Nevertheless, the response of concrete structures subjected to severe dynamic loading differs from their static behaviour, on a structural level but also on a material level. READ MORE
