    Sammanfattning : .... LÄS MER

  3. 2. Restraint Effects in Early Age Concrete Structures

    Författare :Majid Al-Gburi; Björn Engström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : One of the widespread issues in concrete structures is cracks occurring at early age. Cracks that appear in the young concrete may cause early start of corrosion of rebars or early penetration of harmful liquids or gases into the concrete body. LÄS MER

  4. 3. Restraint in structures with young concrete : Tools and estimations for practical use

    Författare :Majid Al-Gburi; Carsten Vogt; Luleå tekniska universitet; []

  5. 4. Investigations on moisture damage-related behaviour of bituminous materials

    Författare :Umaru Bagampadde; Ulf Isacsson; Manfred Partl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture damage; State-of-the-Art; Stripping; Moisture sensitivity; Bituminous materials; Construction engineering; Konstruktionsteknik;

    Sammanfattning : This doctoral thesis presents results of literature review on classical and contemporary aspects of stripping, as well as experimental investigations on moisture damage as influenced by bituminous materials. Previous research in the area of moisture damage was reviewed and synthesized into a state-of-the-art. LÄS MER

  7. 5. Assessment of Concrete Bridges : Models and Tests for Refined Capacity Estimates

    Författare :Niklas Bagge; Anders Carolin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Optimising the strategy for repairing, upgrading and replacing bridges in the European Union, and elsewhere, is becoming increasingly important due to ageing of the bridge stock, continuously increasing load requirements and budgetary limitations. Thus, there is a clear need to identify or develop, and implement, refined methods for assessing existing bridges in order to determine the most cost-effective options and actions to extend their lives, increase their capacities or replace them.
