1. Leaching of concrete : experiments and modelling
Sammanfattning : Many concrete dams, and other concrete structures within the hydropower industry are old and in a more or less severe state of degradation. Leaching is, together with freeze-thaw, the most common degradation problem in Swedish hydraulic concrete structures. LÄS MER
2. Behaviour of fracture process zones in concrete influenced by simultaneously applied normal and shear displacements
Sammanfattning : The thesis deals with the determination of the post peak behaviour of concrete in pure tension, and combined tension (compression) and shear. A test arrangement has been developed in order to determine the post peak behaviour of concrete expressed as stress - displacement curves. LÄS MER
3. Högpresterande betongs hydratation, struktur och hållfasthet
Sammanfattning : Syftet med projektet var att jämföra egenskaper hos s k högpresterande betong, d v s betong med mycket låga vattenbindetal (vbt) med motsvarande egenskaper hos normala betongkvaliteter. Studerade egenskaper är hydration, hållfasthetstillväxt och fukttransportegenskaper. LÄS MER
4. Studies on the frost resistance of natural stone
Sammanfattning : This work deals with the effects of freeze-thawing on the deterioration of some types of natural stone, especially stones frequently used in old buildings in Sweden. Laboratory studies were performed mainly on Gotland sandstone. This stone has been widely used in old buildings in the whole Baltic region, and is often badly deteriorated. LÄS MER
