Engineering Properties of Lightly Cemented Dredged Soil
This paper presents results from a series of experiments which were conducted to assess engineering properties of lightly cemented very high moisture soil (VHMS). Dredged soil was collected from a dredged disposal facility near the port of Mobile, Alabama. Twelve different stabilized VHMS mixtures were prepared using two water contents (liquid limit and 100%), two cement types (portland-limestone cement and ordinary portland cement), and three cement contents (2.5, 5.0 and 10% of dry soil mass). A series of index and unconfined compression (UC) tests were conducted. UC tests were performed after various curing times to investigate trends of compressive strength with time. Specimens made with 2.5% cement showed no notable improvement of shear strength while higher cement contents (i.e., 5 and 10%) resulted in a meaningful improvement in shear strength. Results indicated that chemical cement reactions are controlled by the content of each component in the mixture. Further, UC results demonstrate an increasing trend of compressive strength with cure time as a result of hydration and pozzolanic reactions.
