The reuse of dredged soil as a construction material offers an environmentally sustainable
solution to the growing problem of sediment disposal from waterways and ports. However,
dredged soils often possess poor engineering propertiessuch aslow strength and high moisture
content, making them unsuitable for direct use in construction. This study investigates the
stabilization of dredged soil using Ordinary Portland Cement (OPC) and Ground Granulated
Blast Furnace Slag (GGBS) asstabilizing agents. Various proportions of OPCand GGBS were
blended with dredged soil to assessimprovementsin strength, workability. Laboratory testssuch
as Atterberg limits, compaction, were conducted to evaluate the performance of treated
samples. The results indicate that partial replacement of OPC with GGBS not only enhances
the mechanical properties of the stabilized soil but also reduces cement consumption, leading
to a more cost-effective and eco-friendly solution. This approach promotes the sustainable
utilization of industrial and marine waste materials in geotechnical engineering applications.
