摘要

Dredged marine sediments (DMS), waste material generated by the maintenance activities in ports and harbors can be utilized as a promising resource in construction applications. Sustainable construction advocates the necessity of selecting materials based on geographical context, function, and resource availability, emphasizing on locally sourced alternatives. The paper presents a systematic review to explore the possibility of using DMS as an alternative building material. 111 pertinent publications published within the past 20 years were thoroughly analyzed based on the PRISMA 2020 framework, focusing on characterization, stabilization and performance enhancement of DMS in construction, emphasizing on current applications, future research and innovation. Despite the considerable variations in the physical, chemical, and mechanical properties, selection of appropriate stabilization techniques can yield materials suitable for stabilized earth blocks, concrete, mortar, and road construction, with significant improvements in strength and durability reported in numerous studies. DMS had the ability to attain strengths in the range of 30–57 MPa at 28 days when used in mortars, and concretes and more than 8 MPa in road subgrades. By incorporating stabilizers like fly ash, Ground Granulated Blast Furnace Slag (GGBFS) and hemp shiv, compressive strength in the range of 3–16 MPa can be achieved. This value exceeds the minimum standards for non-structural masonry. Also, the flexural performances are enhanced by 42–80%, highlighting that moderate additive incorporation can significantly improve the properties of DMS. These findings confirm that when optimally proportioned DMS can be used as a sustainable replacement in multiple construction applications. Cement, lime, pozzolanic substances, and geopolymer binders are the most commonly used stabilizing agents, there is an increasing focus on environmentally friendly alternatives such as biochar, polymer resins, and natural fibers. Technical analysis on major stabilization mechanisms like cement stabilization, lime stabilization, alkali activated geopolymerization stabilization and biopolymer induced stabilization is discussed offering insights into both conventional and sustainable approaches. This compilation of key insights into reuse potential of DMS will serve as a foundational reference for future investigations on advancing resource conservation and transitioning towards sustainable construction practices.
