  1. 1. Fibre reinforced concrete : fracture mechanics methods applied on self-compacting concrete and energetically modified binders

    Författare :Patrik Groth; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Fibre reinforced concrete (FRC) is a type of building material that is increasing in use. As new types on concrete develops the need to update the knowledge on the use of fibre reinforcement increases. This thesis covers test methods for FRC that ranges from standard beam tests to sophisticated uniaxial tension tests. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Industrial Fibre Concrete Floors : Experiences and Tests on Pile-Supported Slab

    Författare :Jerry Hedebratt; Johan Silfwerbrand; Terje Kanstad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Pile supported floor slabs have often been designed solely in ultimate limit state ULS and then foremost with uniformly distributed loadings UDL. The investigation of serviceability limit state SLS has been of simpler nature, even according to the governing codes of practice. LÄS MER

  5. 4. Steel fibre corrosion in cracks : durability of sprayed concrete

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

    Sammanfattning : Steel fibre reinforced sprayed concrete is common practice for permanent linings in underground construction. Today there is a demand on "expected technical service life" of 120 years. Thin steel fibres could be expected to discontinue carrying load fast with a decrease of fibre diameter caused by corrosion, especially in cracks. LÄS MER

  7. 5. Durability of sprayed concrete : steel fibre corrosion in cracks

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

    Sammanfattning : 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. LÄS MER
