About 

Synopsis:

Land shortage for housing development has long plagued Hong Kong. Since the 1970s, reclamation was widely used in Hong Kong as a long-term solution to increase land supply. Over the years, various reclamation methods and ground treatment techniques had been developed and employed to suit technical requirements and social needs at different times. In response to increasing environmental awareness, non-dredged reclamation with Deep Cement Mixing (DCM) have been introduced to Hong Kong in recent years. The success of deep mixing works relies on a comprehensive quality control/quality assurance system. Key features of the quality control system applied in a deep mixing project in Hong Kong will be introduced. Recommendations will be made on the selection of binder and its corresponding dosage; the prediction of compressive strength; and the specification for compliance. Field data of a trial embankment will be presented and interpreted. The trial embankment performance will be appraised based on the monitoring data.
