|Abstract:||Cement stabilized Singapore marine clay is the material associated with the Stabilized Dredged Fill (SDF) technology practiced in Singapore. Understanding the mixture early-age strength characteristics and how the early-age and later-age strength characteristics are related will significantly improve the current SDF quality control. Flow value tests, laboratory vane shear tests and unconfined compression tests are conducted in this study. Flow value tests are conducted immediately after mixing. Laboratory vane shear tests are conducted immediately after mixing and at early curing ages. The unconfined compression test results reveal that the water/cement ratio is the appropriate parameter depicting the mixture later-age strength. The flow value test results and vane shear test results obtained immediately after mixing both suggest the current SDF quality control practice may be improved. The correlations established between the early-age vane shear strengths and later-age unconfined compression strengths may be used to improve the current SDF quality control.|
