2. The influence of particle shape of coating pigments on their packing ability and on the flow properties of coating colours
Sammanfattning : The influence of particle shape of coating pigments on theirpacking ability and on the flow properties of coating colourshas been investigated. The particle shapes considered werespherical, flaky and acicular (needle-shaped). LÄS MER
3. Aggregates in Concrete Mix Design
Sammanfattning : The importance of studying the behaviour and properties of concrete can be highlighted by considering the fact that concrete is the most used man-made material in the world. The very first step in making concrete is its mix design and deciding the type and amount of constitutes used in the production of concrete which should fulfil the requirements of the final product.

4. Flowability and proportioning of cementitious mixtures
Sammanfattning : Understanding the role of constituents of cementitious mixtures as the most globally used human-made material and their effect on the flowability of the blends is of great importance. A comprehensive understanding of the ingredients of mixtures allows for optimized proportioning of constituents and can lead to a reduction in cement and water demand of the blends. LÄS MER
5. A numerical study on orientational arrest and size segregation of dense particle flows using discrete element modeling
Sammanfattning : The thesis focuses on studying dense particle flows, which are either dry or submerged in a Newtonian fluid through two dimensional numerical simulations using the discrete element method (DEM). The First paper deals with dense suspensions in viscous regime under oscillatory planar shear. LÄS MER
