  2. 1. Rock grouting design: Rheological aspects and radial flow visualizations with ultrasound

    Author : John Shamu; Stefan Larsson; Ulf Håkansson; Liangchao Zou; Chadi El Mohtar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement grouts; grouting; yield stress fluid YSF ; thixotropy; critical shear rate; radial flow; wall slip; Bingham model; Cementbaserade injekteringsmedels; injektering; icke-Newtonska vätskors; tixotropi; kritisk deformationshastigheten; radiella strömning; glidning; Bingham modell; Jord- och bergmekanik; Soil and Rock Mechanics;

    Abstract : The rheological properties of cement-based grouts play a crucial role indetermining the final spread in grouted rock formations. In rheological terms,cement grouts are known to be complex time-dependent yield stress fluids,but their steady flow behavior is often described by the simple Binghamconstitutive law. READ MORE

  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. On the measurement and application of cement grout rheological properties

    Author : John Shamu; Stefan Larsson; Ulf Håkansson; Johan Funehag; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement-based grouts; grouting; yield stress fluid YSF ; thixotropy; critical shear rate; radial flow; wall slip; Bingham model; Civil and Architectural Engineering; Byggvetenskap; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The rheological properties of cement-based grouts play a key role in determining the final spread in grouted rock formations. Rheologically, cement grouts are known to be complex thixotropic fluids, but their steady flow behavior is often described by fitting the simple Bingham constitutive law to flow curve data.

  6. 4. Flow and Rheology of Pulp Suspensions at Medium Consistency

    Author : Tomas Wikström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluidisation; yield stress; agitation; pulp suspension; computational fluid dynamics; fibre properties; turbulence; screening; Bingham model;

    Abstract : Traditionally, development of pulp processing equipment has been based on the accumulation of qualitative knowledge (experience) with respect to the interaction of equipment and pulp suspensions. This way of developing equipment requires several trials and prototypes before the final product and process data can be established. READ MORE
