  2. 16. Material Properties of Bulk Hydrophobic Concrete in a Nordic Environment

    Author : Patrick Rogers; Johan Silfwerbrand; Tang Luping; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkyl alkoxysilane; capillary suction; chloride ingress; concrete; hydrophobic agents; triacylglycerides; Betongbyggnad; Concrete Structures;

    Abstract : Concrete in its unaltered form allows the mass transfer of fluids into and out of its microstructure. These fluids can contain detrimental solutes which change the chemistry of the cement paste and/or the corrosion properties of the reinforcement bars, most noticeably hydrogen carbonates (HCO3-), oxygen (O2) and chloride ions (Cl-).

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

    Author : Ulrika Nyström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SDOF; Concrete; fragment impact; weapon effects; fibre-reinforced concrete; blast wave; numerical simulations; reinforced concrete;

    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

  6. 19. Durability of sprayed concrete : steel fibre corrosion in cracks

    Author : Erik Nordström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : A combination of sprayed concrete technique and steel fibre technology gives obvious advantages when saving the work needed to place conventional reinforcement. In rock strengthening applications this is most accentuated. Sprayed concrete in general, made by skilled workmen, will generally be of high quality and good durability. READ MORE

  7. 20. Self-compacting concrete : properties of fresh and hardening concrete for civil engineering applications

    Author : Sofia Utsi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This licentiate thesis consists of three papers, A-C. In Paper A the consequence of using self-compacting concrete for civil engineering applications regarding the fresh and young stage and possible consequences on production techniques are studied. READ MORE
