  1. 1. Chloride initiated reinforcement corrosion in marine concrete

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Paul Sandberg; Lund University.; Lunds universitet.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; w c ratio; cover thickness; chloride penetration; service life prediction; corrosion cells; chloride thresholds; field exposure tests; marine concrete; pozzolans; reinforcement corrosion; chloride binding; Building construction; Byggnadsteknik;

    Abstract : Factors affecting the total chloride threshold for initiation of pitting corrosion in reinforced concrete were investigated by means of field and laboratory exposure tests. Factors affecting the chloride penetration into concrete were also investigated by means of field tests. The thesis consists of a summary (86 p.) and 11 papers attached. READ MORE

  2. 2. A NEW APPROACH TO CRACK CONTROL FOR REINFORCED CONCRETE - An investigation of crack widhts close to the reinforcement and the correlation to service life

    University dissertation from The Division of Structural Engineering

    Author : Kristian Tammo; Lund University.; Lunds universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete cover; corrosion; Crack width; steel stress and service life;

    Abstract : One of the most important factors governing durability of concrete structures is reinforcement corrosion, and to prevent degradation associated with it, it is desirable to use large concrete covers. However, if the concrete cover is increased, the majority of design methods will predict that the crack widths at the concrete surface increase significantly. READ MORE

  3. 3. Subsurface dams in water resource management methods for assessment and location

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Imran Ali Jamali; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subsurface dams; Groundwater; GIS; Regolith thickness; Groundwater; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Natural groundwater storage can be improved by constructing a subsurface barrier that is a subsurface dam, in order to capture the subsurface flows and raise the groundwater levels (GWLs) in the sediment layers. Subsurface dams are preferable to surface dams because of lower evaporation, higher functionality, lower cost of construction, lessened risk for contamination and the possibility of utilizing land over the dam.

  4. 4. Studies of the Arctic Ocean sea ice cover and hydrothermal heat fluxes

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Christian Stranne; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Arctic climate sensisitvity;

    Abstract : Since reliable ice extent estimates from satellite data became available in 1979 the Arctic sea ice cover has followed a declining long term trend. Over the last decade the decline has accelerated with record low sea ice extents recorded in 2002, 2005, 2007 and 2012. READ MORE

  5. 5. Sea Ice Concentration Estimation and Ice Type Classification from Dual-Frequency Satellite Synthetic Aperture Radar

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Wiebke Aldenhoff; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sea ice concentration; sea ice; SAR imaging; sea ice classification; Fram Strait;

    Abstract : The sea ice cover in the Arctic has undergone dramatic changes in recent years. The perennial sea ice extent is decreasing by 12.2 % per decade while annual mean sea ice thickness has decreased by more than 2 m for the central Arctic Basin from 1975 to 2012. READ MORE
