A comprehensive review of dredged marine sediments -multiple roles of utilization in cement-based materials and construction products.

Dredged marine sediments (DMS), produced during harbor maintenance and waterway development, pose significant environmental and disposal challenges. Increasingly, research has focused on their potential reuse in construction materials, offering a sustainable alternative to waste disposal and promoting resource conservation. This paper provides a comprehensive review of the potential application of DMS in cementitious systems, exploring their multiple roles as alternative binders or aggregates in sustainable practices. Key properties and treatment methods of DMS are summarized, and the mechanical and durability of DMS-incorporated materials are critically evaluated, highlighting their suitability and challenges. The carbon emissions of DMS blended cement are calculated and found to be 16.58 % lower than those of OPC. Further research is needed to standardize processing techniques, evaluate long-term performance, and facilitate large-scale adoption in sustainable construction.
