  2. 6. Mixing Processes for Ground Improvement by Deep Mixing

    Author : Stefan Larsson; KTH; []
    Keywords : Deep Mixing; Lime cement columns; Mixing mechanisms; Mixture quality; Field test; ANOVA; Variance reduction.;

    Abstract : The thesis is dealing with mixing processes havingapplication to ground improvement by deep mixing. The mainobjectives of the thesis is to make a contribution to knowledgeof the basic mechanisms in mixing binding agents into soil andimprove the knowledge concerning factors that influence theuniformity of stabilised soil.

  5. 8. Strength variability in lime-cement columns and its effect on the reliability of embankments

    Author : Mohammed Salim Al-Naqshabandy; Stefan Larsson; Lars Olsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lime-cement; embankments;

    Abstract : Ground improvement by deep mixing (DM) is a generic term used for a number of methods in which a binding agent, often lime and/or cement, is mechanically mixed with the soil to increase its engineering properties. The inherent variability with respect to the engineering properties of the improved soil is high due to the variations in geology and the complex mixing process. READ MORE

  6. 9. Ground Improvement by Dry Deep Mixing Lime-Cement Column Panels as Excavation Support

    Author : Razvan Ignat; Stefan Larsson; Sadek Baker; Sven Liedberg; Masaki Kitazume; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Many urban areas near the coastal regions of Sweden are characterized by post-glacial clay deposits with very low undrained shear strength and high compressibility. Column type ground improvement by the Deep Mixing, DM, method using a binder mixture of lime and cement is commonly used in areas with poor soil conditions due to its cost-effectiveness, predominantly for settlement reduction and to improve the stability of embankments.

  7. 10. Deformation Behavior of Lime/Cement Column Stabilized Clay

    Author : Sadek Baker; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Deep stabilization of clay with lime/cement columns has lately become one of the most frequent methods for improvement of soft clays. The method is cost effective, as it results in a drastic reduction of settlement. The theories used for design were originally developed for lime columns. READ MORE
