  1. 1. Chloride initiated reinforcement corrosion in marine concrete

    Författare :Paul Sandberg; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; w c ratio; cover thickness; chloride penetration; service life prediction; corrosion cells; chloride thresholds; field exposure tests; marine concrete; pozzolans; reinforcement corrosion; chloride binding; Building construction; Byggnadsteknik;

    Sammanfattning : Factors affecting the total chloride threshold for initiation of pitting corrosion in reinforced concrete were investigated by means of field and laboratory exposure tests. Factors affecting the chloride penetration into concrete were also investigated by means of field tests. The thesis consists of a summary (86 p.) and 11 papers attached. LÄS MER

  3. 2. Chloride transport and chloride threshold values : studies on concretes and mortars with Portland cement and limestone blended cement

    Författare :Dimitrios Boubitsas; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Mortar; Concrete; Corrosion; Reinforcement; Chloride ions;

    Sammanfattning : Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. LÄS MER

  4. 3. Prediction of Chloride Penetration into Saturated Concrete Multi-Species Approach

    Författare :Olivier Truc; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffusion; concrete; multi-species; chloride; corrosion; migration;

    Sammanfattning : The cost due to rehabilitation of corroded reinforced concrete structures is a worldwide matter of concern. The mechanisms of reaction-diffusion involved during the transport of chloride ions into saturated concrete, which are initiating the corrosion process, are therefore studied in this thesis. LÄS MER
