  2. 11. Novel approaches for monitoring effects of steel corrosion in reinforced concrete

    Author : Andreas Alhede; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reinforced Concrete; Neutron and X-ray Computed Tomography; Corrosion; Distributed Optical Strain Sensing;

    Abstract : Corrosion of steel reinforcement is a common deterioration mechanism in reinforced concrete structures. This deterioration impacts the safety of the structure and may require extensive repair and maintenance work. There is currently no method available for accurately measuring internal corrosion damage non-destructively. READ MORE

  4. 12. Structural Effects of Reinforcement Corrosion in Concrete Structures

    Author : Mohammad Tahershamsi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experiments; load-carrying capacity; anchorage; pitting; FE analysis; natural corrosion; Bond properties; damage assessment; modelling.; structural behaviour; reinforced concrete structures; 3D optical scanning; inspection;

    Abstract : Reinforcement corrosion is a common cause of deterioration in reinforced concrete.The corrosion mechanism involved and the consequent structural behaviour ofdeteriorated reinforced concrete members have been studied by several researchers. READ MORE

  5. 13. On the low primary water stress corrosion cracking susceptibility of weld deformed Alloy 690

    Author : Rickard Shen; Pål Efsing; Jonas Faleskog; Grace Burke; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : It has been shown in recent years that the nickel-base Alloy 690 can become susceptible to stress corrosion cracking (SCC) in the primary water of nuclear power plants with pressurized water reactors if it has been sufficiently deformed at room temperature. Although the material is not intentionally used in a deformed state, it can become deformed by various manufacturing processes. READ MORE

  6. 14. Structural Behaviour of Deteriorated Concrete Structures

    Author : Kamyab Zandi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FE analysis; concrete; stirrup; corrosion; bond; pull-out test; frost;

    Abstract : A growing concern for better assessment of existing concrete structures has revealed a need for improved understanding of the structural effects of deterioration. The two most common causes of deterioration in concrete structures are freezing of the concrete and corrosion of the reinforcement. READ MORE

  7. 15. Modeling and Simulation of Weld Hot Cracking

    Author : Joar Draxler; Lars-Erik Lindgren; Jonas Edberg; Paul Åkerström; Jesper Hattel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : Several alloy systems are susceptible to weld hot cracking. Weld hot cracking occurs by fracture of liquid films, normally grain boundary liquid films, at the late stage of the solidification of the weld. The cracks can be small and therefore difficult to detect by nondestructive test methods. READ MORE
