11. On Mesoscale Modelling of Coupled Chloride-Moisture Transport in Concrete
Sammanfattning : The service life behaviour of concrete structures is highly influenced by the ingress of chloride ions. At sufficiently high concentrations, chloride ions can initiate corrosion of embedded reinforcement bars, which may substantially reduce the structure's bearing capacity and ultimately lead to structural collapse.

12. Baggy paper webs : Effect of uneven moisture and grammage profiles in different process steps
Sammanfattning : One of the problems encountered in paper converting is caused by the occurrence of "baggy webs", which essentially is when the tension profile of the paper web is uneven. In an area with low tension the paper is longer, which results in bagginess. LÄS MER
13. Diagnosis of Moisture in Transformer Insulation - Application of frequency domain spectroscopy
Sammanfattning : This thesis presents application of dielectric response measurements for identifying condition of high voltage insulation in power transformers. Results of such measurements, incorporated with different modelling techniques, allow to estimate moisture content in solid part of transformer insulation. LÄS MER
14. High Clay Content Cellulose Nanocomposites for Mechanical Performance and Fire Retardancy
Sammanfattning : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. LÄS MER
15. Moisture content measurement in the wood industry
Sammanfattning : In the wood industry, determination of the moisture content (mc) with a highaccuracy is of great importance. The green mc is important for optimisation of thewood drying process at sawmills, whereas the mc of dried boards is of interest for thefurther processing and final use of the boards. LÄS MER
