In-Situ Deep Soil Mixing for Solidification of Soft Estuarine Sediments Shear Strength
The paper reviews the use of Cement Deep Soil Mixing CDSM for solidification and stabilization of contaminated sediments and describes the shear strength behavior of solidified soft estuarine sediments from Newark Bay, near the mouth of the Passaic River, New Jersey. The objective of the study was to evaluate the shear strength gain with time for samples of solidified soft sediments following Cement Deep Soil Mixing (CDSM). An understanding of shear strength gain with time helps to determine the feasibility of conventional dredging/extraction methods once the sediments have been stabilized and allowed to cure. The results of the study show CDSM slurry mixtures, as low as 7% in cement content, result in significant solidification and strength gain of in-situ sediments under ambient conditions. Although the strength gain was significant, it was not so high that sediment dredging would become problematic or would require unconventional dredging equipment.
