Abstract— This paper describes study on permeation of ultra-fine particle cement grout into sandy ground. The cement grouting method was one of the improvement methods to strengthen the sandy ground. However, the conventional cement grout was difficult to permeate into sandy ground. The purpose of this study is to clarify the permeation of the ultra-fine particle cement grout into dry and saturated sands. The author conducted both column and model ground injection tests to examine the permeability of ultra-fine particle cement grout. As a result, ultra-fine cement grout had high permeability against finer sand regardless of dry and/or saturated conditions and the stabilized area was wider.
