Abstract
Deep cement mixing method (DCM) is used to improve the quality of various ground type and its technical development proceeding based on performance improvements of solidification materials and mixing techniques with ground soil. In this study, it was possible to improve silty clay ground soil had 1 to 3 MPa compressive strength using solidification material that composed mainly circulating fluidized bed combustion (CFBC) power plant fly ash and reduce standard deviation of strengths from over 1.0 MPa to 0.322 MPa using improved auger bits in field test to forming more uniform bulbs than in case of using existing auger bit.
