1. Moisture and Chloride Transport in Concrete
Abstract : Material properties pertaining to the physical phenomena of mass transport in concrete are important for the durability of concrete structures, and they can ultimately be derived from material heterogeneities found at different subscales. On the mesoscale level, these heterogeneities are mainly characterized by the presence of embedded aggregates in the cement paste, together with cracks. READ MORE

2. Time dependent material properties of shotcrete for hard rock tunnelling
Abstract : In this thesis different mechanical properties for shotcrete (sprayed concrete) such as compression strength, bond strength, bending tensile strength, elastic modulus, free and restrained shrinkage as a function of its age was investigated. One of the main issues was to investigate the difference between ordinary cast concrete and shotcrete. READ MORE

3. Microstructure and plastic deformation of textured CVD alumina coatings
Abstract : It is known that the wear performance of α-alumina coatings produced by chemical vapor deposition (CVD) is significantly influenced by the type and degree of texture. However, the main reasons behind this behavior are not fully understood. This thesis contains studies of two related topics for increasing the understanding of α-alumina coatings. READ MORE

4. On Mesoscale Modelling of Coupled Chloride-Moisture Transport in Concrete
Abstract : 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.

5. Structural Behaviour of Concrete Railway Sleepers
Abstract : The railway concrete sleeper is an important part of the railway track structure. The sleeper member requires substantial engineering skills during the design and manufacturing process in order to fulfil the requirements set by modern train traffic. READ MORE
