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

    Author : Dimitrios Boubitsas; RISE; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Corrosion of steel in concrete at various moisture and chloride levels

    Author : Johan Ahlström; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel; rebar; concrete; corrosion; chloride threshold level; moisture;

    Abstract : About 7000 concrete bridges in Sweden were built before 1965. The annual cost for maintenance of these bridges is about 0.6% of their total value. The cooling water tunnels at Swedish nuclear power plants have been exposed to seawater for about 30-40 years. READ MORE

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

    Author : Anders Lindvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrosion; de-icing salt; road conditions; marine conditions; service life predictions; reinforcement; chloride; concrete; moisture conditions; environmental actions;

    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

  7. 5. Personality, Health and Mortality of Workers in a PVC Production Plant in Sweden A longitudinal study

    Author : Margareta Ardeberg; Miljö- och energisystem; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mortality; disease; recovery; personality alterations; solvents exposure; PVC; polyvinyl chloride; Sjöbring personality psychology; behavioural toxicology; MNT scale; MFS scale; Eysenck; Psychology; Psykologi;

    Abstract : A longitudinal study was initiated in a PVC production plant in 1967. It was repeated in 1987. A cohort of 101 workers was followed. The aim of the 1967 study was, after a heavy rise in absenteeism and sick leave, to analyze perceptions of work environment and health. READ MORE
