  • Size analysis of sand by a sedimentation technique

    The particle size distributions of sand-size material can be determined either directly by microscopic measurement or indirectly by sieving or by sedimentation techniques. Routine size analyses by microscopic measurements are impractical because they are too time consuming although other properties such as grain shape or roundness can be

  • Sieving methods of sieve analysisRETSCH

    Sieving methods of sieve analysis. During sieving the sample is subjected to vertical movement (vibratory sieving) or horizontal motion (horizontal sieving). With tap sieve shakers both movements are superimposed. During this process the particles are compared with the apertures of every single sieve. The probability of a particle passing

     · The term may apply to other granular materials too. This differs from the size of a crystallite which refers to the size of a single crystal within a particle or grain. Many crystals can be composed of a single grain. Granular material can vary from very small colloidal particles to boulders through clay silt sand gravel and cobbles.

  • A new biogrouting method for fine to coarse sand

     · Permeation grouting using cement is widely used for ground improvement. However this method can only be used for coarse sand or gravel. To overcome this problem permeation grouting using biogrout through a microbially induced calcium carbonate precipitation method has also been developed. Biogrout is finer and thus can permeate through fine sand.
