4. 2. Modelling of Bingham Suspensional Flow : Influence of Viscosity and Particle Properties Applicable to Cementitious Materials

   Author : Annika Gram; Björn Lagerblad; Ulrich Diederichs; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-Compacting Concrete; SCC; Fresh concrete flow; Numerical simulation; Viscosity; Open channel flow;

   Abstract : Simulation of fresh concrete flow has spurged with the advent of Self-Compacting Concrete, SCC. The fresh concrete rheology must be compatible with the reinforced formwork geometry to ensure complete and reliable form filling with smooth concrete surfaces. READ MORE

5. 3. Controlled Polymer Grafting from Nanoparticles for the Design of Dielectric Nanocomposites

   Author : Martin Wåhlander; Eva Malmström; Anna Carlmark; Henrik Hillborg; Sanat K. Kumar; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The interest for polymeric nanocomposites has rapidly grown during the last decades, fuelled by the great potential and superior properties of nanoparticles (NPs). The production volumes of commercial NPs have increased exponentially during the last ten years, and the quality has been significantly improved. READ MORE

6. 4. Modelling electrical properties of composite materials

   Author : Eva Mårtensson; KTH; []
   Keywords : ;

   Abstract : Composite field grading materials are used to avoid stressconcentrations in high voltage applications such as cableaccessories and generator or motor end windings. The compositematerials consist of an insulating matrix filled with suitableconducting or semi-conducting particles. Silicon carbide (SiC)powder is one such filler that is being employed. READ MORE

7. 5. An investigation into some aspects for foamed bitumen technology

   Author : May Namutebi; Björn Birgisson; Alvaro Guarin; Umaru Bagampadde; Baoshan Huang; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foamed bitumen; Binder ageing; Aggregate coating; Compaction; Mix design; Aggregate porosity; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : Despite applications of foamed bitumen technology in pavement construction in various places around the world, there are still several aspects about this technology that are not clear. In addition, knowledge on foamed bitumen technology is mainly empirical and lacks scientific basis. READ MORE
