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

    University dissertation from Stockholm : KTH

    Author : Anders Selander; KTH.; [2010]
    Keywords : 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;

    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

  2. 2. 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

  4. 4. Environmental actions on concrete exposed in marine and road environments and its response - Consequences for the initiation of chloride induced reinforcement corrosion

    University dissertation from Chalmers University of Technology

    Author : Anders Lindvall; Chalmers tekniska högskola.; Chalmers University of Technology.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Samhällsbyggnadsteknik och arkitektur; Civil engineering and architecture; chloride; concrete; corrosion; de-icing salt; environmental actions; marine conditions; moisture conditions; reinforcement; road conditions; service life predictions;

    Abstract : The object of the study presented here has been to describe, further explain and model the influence of the exposure conditions on reinforced concrete structures and the consequences on their expected service life. The focus has been on investigating and quantifying the exposure conditions for structures in marine and road conditions exposed to chloride ions. READ MORE

  5. 5. Chloride Transport in Concrete under the Frost Action – An Experimental Study

    University dissertation from Chalmers University of Technology

    Author : Bo Li; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsmaterial; Construction materials; chloride; transport; concrete; frost action; freeze-thaw cycles; temperature; water uptake; chloride profile;

    Abstract : Frost-induced ingress of chloride in concrete is one of the typical transport phenomena of aggressive substances when structures expose to severe environments such as marine tidal zone and de-icing highway in winter seasons. It is well known that Chloride ingress in concrete causes the reinforcement corrosion. READ MORE
