  1. 11. 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

  3. 12. Industrial Application of Sulfur Concrete An Environment-friendly Construction Material

    Författare :Amon Raphael Makenya; KTH; []
    Nyckelord :Sulfur binder; Chempruf modifyer; Sulfur Concrete SC ; Durability; SC market survey; SC Applications; Environment.;

    Sammanfattning : Sulfur Concrete (SC) is a thermoplastic constructionmaterial, of mineral aggregates and modified sulfur as binder.Elemental sulfur has now a low smelting point (120oC) and appears in two solid allotropic forms,separated by considerable contraction. Hence, the need formodification to delay the transition. LÄS MER

  4. 13. Wave energy conversion and the marine environment : Colonization patterns and habitat dynamics

    Författare :Olivia Langhamer; Anders Berglund; Jan Sundberg; Andrew Gill; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial reefs; benthos; biodiversity; biofouling; colonization; environmental impact; fish; shellfish; Mytilus edulis; renewable energy; wave power; Biology; Biologi; Animal Ecology; Zooekologi;

    Sammanfattning : A wave energy park has been established on the Swedish west coast outside Lysekil and pioneer work about its interactions with the marine environment has been conducted. So far, little is known about the effects of offshore energy installations on the marine environment, and this thesis assists in minimizing environmental risks as well as in enhancing potential positive effects on the marine environment.

  5. 14. Man-made structures as habitat for marine faunal assemblages

    Författare :Mathias H. Andersson; Sören Nylin; Hans Kautsky; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : Artificial reefs are structures placed in the sea to promote marine life. Although constructions such as oil-rigs, wind farms, bridges and pier pilings are built for other purposes, they could be regarded as artificial reefs as they add new surfaces in the oceans, susceptible to colonization by marine organism.

  7. 15. Service Life Assessment of Harbor Structures - Case studies of chloride ingress into concrete and sheet piling corrosion rates

    Författare :Henrik Wall; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chloride ingress; sampling methods; corrosion rates; sheet piling; ultra-sonic measurements; service life; durability; quay structures; harbor structures;

    Sammanfattning : The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where the steel sheet pile walls often have cap beams of reinforced concrete. LÄS MER
