Abstract
The Cement Deep Soil Mixing (CDSM) method is an in situ soil treatment technology that introduces and mixes cementitious materials with native soils using hollow-stem rotating shafts equipped with a cutting tool at the tip and mixing paddles above the tip. The successful use of the soil-cement produced by CDSM relies on the selection of acceptance criteria and construction quality control during the in situ soil mixing process. Two CDSM projects for the Port of Oakland are used as case examples to present the acceptance criteria set and the execution of the quality control program for the soil mixing work. This quality control program ensures that the geometric and material design parameters of the CDSM structure have been obtained. The data acquired from these two projects are presented and compared with strength data from two other projects to illustrate the influence of acceptance criteria over the CDSM products.

Quality Control of Cement Deep Soil Mixing Work for the Port of Oakland Projects
