Lightly cementing marginal materials to improve sustainability and economic competitiveness near ports and harbors.

摘要

Large amounts of dredged sediment are removed from ports and river channels annually to maintain necessary depths in the maritime industry. The most common management approach for dredged soils throughout the southeast US is disposal in confined facilities. This may be the most feasible approach for ports with modest amounts of dredged soil and ample capacity for disposal. However, there is likely a more feasible option for some ports desiring to increase dredged soil containment capacity.;This thesis evaluates the beneficial reuse of dredged soils after lightly cementing with 5.0% or less cement by slurry mass. A previously conducted survey was interpreted prior to performing a literature review, testing, and performing sustainability calculations for reuse of dredged soil when lightly cemented. There were 239 experiments performed as part of this thesis to evaluate the feasibility of utilizing dredged soils after lightly cementing for beneficial reuse projects near ports.
