  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 : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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. Lignin Extraction from Black Liquor - Properties of the Liquors and Sulphur Content in the Lignin

    Author : Ali Seid Moosavifar; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat-treatment; lignin precipitation; boiling point elevation; lignin; alkalisation; biofuel; properties; viscosity; Black liquor; combustion of lignin; lignin modification; viscosity correlations.;

    Abstract : Kraft lignin isolated by precipitation can be considered as being a valuable renewable source of energy and material. Removing lignin from black liquor is also advantageous as it decreases the load on the recovery boiler, which is usually the limiting factor in the production of kraft pulp. READ MORE

  6. 4. Study on some phenomena of slag in steelmaking process

    Author : Liushun Wu; Sichen Du; Carlo Mapelli; KTH; []
    Keywords : Slag viscosity; calcium fluoride; fluid viscosity with particles; mixture viscosity; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The present work is to study slag phenomena in steelmaking process. In order to attain thegoal, a number of high temperature experiments and simulation experiments were carried out. Four master slags were used to study the effect of CaF2 on slag viscosity. READ MORE
