  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

    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. READ MORE
