  3. 3. Moisture Conditions and Frost Resistance of Concrete in Hydraulic Structures

    Detta är en avhandling från Building Materials, LTH, Lund University

    Författare :Martin Rosenqvist; Lund University.; Lunds universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic Structures; Hydro Power; Concrete Dams; Concrete; Frost Resistance; Scaling; Spalling; Moisture Absorption; Macroscopic Ice Lens Growth;

    Sammanfattning : Owing to the winter conditions in Sweden, the effects of frost action may have a considerable impact on the deterioration of concrete. Both superficial and internal damage, which are suspected to have been caused by frost action, have been found in concrete in hydraulic structures. LÄS MER

  4. 4. Frost-induced deterioration of concrete in hydraulic structures : Interactions between water absorption, leaching and frost action

    Detta är en avhandling från Building Materials, LTH, Lund University

    Författare :MARTIN ROSENQVIST; Lund University.; Lunds universitet.; [2016-09-14]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenbyggnader; Dammar; Betong; Cement; Vattenabsorption; Vattenmättnadsgrad; Nedbrytning; Frostbeständighet; Spjälkning; Makroskopisk islinsbildning; Urlakning; Synergi; Hydraulic structures; Dams; Concrete; Cement; Water absorption; Degree of saturation; Deterioration; Frost resistance; Spalling; Macroscopic ice lens growth; Leaching; Synergy;

    Sammanfattning : Frost deterioration of concrete can result in severe consequences to the safety, durability and functionality of a structure since it impairs the strength of the concrete. Frost damage may occur to structures that are in contact with water and subjected to frost action. LÄS MER

  5. 5. The influence of ageing on the salt-frost resistance of concrete

    Detta är en avhandling från Division of Building Materials, LTH, Lund University
