The coastal engineering of land reclamation is increasingly important for space retention and creation in the context of sea-level rise and limited land area in coastal regions. Meanwhile, a huge amount of marine dredged sediment (MDS) is generated annually and disposed of as waste, causing serious environmental problems. To minimize such disposal and turn waste into resources for coastal engineering, MDS can be upcycled for in-situ marine sediment concrete (MSC) production. As a major concern, the durability of MSC remains elusive with an inadequate scientific understanding. In this paper, the durability of concrete involving MDS was investigated comprehensively from three aspects: physical attack, chemical attack, and inner quality. The accessible porosity was identified as the key factor affecting the durability of MSC. Practical measures were explored for the durability design of MSC. This study can pave the way for the sustainable use of MDS for marine construction, coastal protection, and land reclamation.
