1. 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

3. 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
4. Modelling of Transport Processes Involved in Service Life Prediction of Concrete : Important Principles
Sammanfattning : The main focus in this licentiate thesis is a description of the environmentally introduced action of diffusing and chemically reactive (e.g. carbonation and chemical-physical adsorption-desorption) matter in the pore solution and in the air-filled space in the pore system of the material.

5. Development of strength and heat of hydration of young concrete at low temperature - influence of granulated blast furnace slag, silica and limestone
Sammanfattning : The work presented in this licentiate thesis was carried out within the project task Use of industrial by-products and filler in concrete, part Early-age strength development at low temperatures in concrete with mineral additions/fillers. To improve the understanding and to increase the data available, the study investigated the development of compressive strength and heat of hydration while curing at 5°C compared with curing at 20°C.
