  1. 11. Penetrability due to filtration tendency of cement based grouts

    Författare :Daniel Eklund; Håkan Stille; Gunnar Gustafson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; grout; grouting; penetrability; filtration tendency; Byggnadsteknik; Building engineering; Byggnadsteknik;

    Sammanfattning : Grouting as a method of strengthening and sealing rock, soil and concrete is widely used. The possibilities of sealing structures are of great importance from both an economical and environmental point of view. The cost of grouting has in certain projects been as high as the cost for the blasting and excavation of the tunnel. LÄS MER

  3. 12. On the measurement and application of cement grout rheological properties

    Författare :John Shamu; Stefan Larsson; Ulf Håkansson; Johan Funehag; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 13. From Silica Nano-Particles to Silica Gels and Beyond - Salt Induced Aggregation of Silica Nano-Particles and the Stability of Resultant Gels

    Författare :Christian Sögaard; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silica; Nanoparticles; grouting; Specific ion effects; Nanomaterial;

    Sammanfattning : Aqueous silica nanoparticle suspensions are widely available and used within a number of industries. A relatively new area of application is as a grouting material for sealing narrow fractures in tunnels. LÄS MER
