  2. 1. Fibre reinforced concrete : fracture mechanics methods applied on self-compacting concrete and energetically modified binders

    Author : Patrik Groth; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Fibre reinforced concrete (FRC) is a type of building material that is increasing in use. As new types on concrete develops the need to update the knowledge on the use of fibre reinforcement increases. This thesis covers test methods for FRC that ranges from standard beam tests to sophisticated uniaxial tension tests. READ MORE

  4. 2. 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

  6. 4. Chloride Transport in Concrete under the Frost Action – An Experimental Study

    Author : Bo Li; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; chloride; concrete; freeze-thaw cycles; water uptake; chloride profile; frost action; transport;

    Abstract : Frost-induced ingress of chloride in concrete is one of the typical transport phenomena of aggressive substances when structures expose to severe environments such as marine tidal zone and de-icing highway in winter seasons. It is well known that Chloride ingress in concrete causes the reinforcement corrosion. READ MORE

  7. 5. Steel fibrous cement based composites: material and mechanical properties : behavior in the anchorage zones of prestressed bridges

    Author : Lutfi Ay; KTH; []
    Keywords : process improvement of bridges; prestressed concrete; high performance concrete;

    Abstract : This PhD thesis is divided into two parts. Part one dealswith the development of the material and the mechanicalproperties of Steel Fibrous Cement Based Composites (SFCBC) forimproving bridge design and construction. It familiarizes thehydration mechanisms of the high performance concrete with thehelp of Powers´ and Jensen´s models. READ MORE
