1. Prediction of Chloride Penetration into Saturated Concrete Multi-Species Approach
Sammanfattning : The cost due to rehabilitation of corroded reinforced concrete structures is a worldwide matter of concern. The mechanisms of reaction-diffusion involved during the transport of chloride ions into saturated concrete, which are initiating the corrosion process, are therefore studied in this thesis. LÄS MER
2. DIFFUSION OF IONS IN WOOD
Sammanfattning : Wood sourced from well managed plantations or forests, is a renewable material with many advantages over non-renewable (fossil) material, and also wood lignocelluloses are the only type of biomass that is a seasonal-independent product. In addition to direct utilization as a building material, major uses of wood are currently for making pulp and paper products, and fuel. LÄS MER
3. On the sorption and diffusion of radionuclides in bentonite clay
Sammanfattning : .... LÄS MER
4. Chloride initiated reinforcement corrosion in marine concrete
Sammanfattning : 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. LÄS MER
5. Mechanisms of salt frost scaling on portland cement-bound materials: studies and hypothesis
Sammanfattning : A hypothesis regarding the mechanism causing salt frost scaling on Portland cement-bound materials is described. It is assumed that deterioration is due to osmotic micro ice body growth, as has been previously proposed for frost deterioration of moisture-isolated specimens of cement-bound materials. LÄS MER
