20.500.12556/DiRROS-23254 Stabilization of dredged marine sediment using biopolymer The frequent dredging of sediments from port areas often leads to the rapid accumulation of excess material, potentially resulting in landfill challenges. Dredged marine sediments typically exhibit high water content, a significant proportion of fine-grained soil, limited bearing capacity, substantial settlement tendencies, and low shear strength. Addressing these issues is imperative for construction projects on such soil types. Recent trends in soil stabilization have witnessed the rising popularity of sustainable bio-binders, particularly biopolymers, owing to their environmentally friendly attributes and extensive use in various geoenvironmental applications. This study investigates the utilization of four different types of biopolymers for the stabilization of marine dredged sediment sourced from the Port of Koper, Slovenia. The research investigates the influence of biopolymer incorporation on the geotechnical properties of biopolymer-treated sediment through Atterberg limits and cone falling tests. In addition, samples were analyzed by scanning electron microscopy (SEM) to elucidate the interaction between biopolymer and the sediment. The findings demonstrate a significant enhancement of undrained shear strength with the addition of biopolymers to the sediment. The formation of hydrogel within the soil pores not only increases the sediment consistency but also positively affects the soil's shear strength. marine sediment biopolymer stabilization consistency undrained shear strength morski sediment biopolimer stabilizacija konsistenca nedrenirana strižna trdnost true false true International Society for Soil Mechanics and Geotechnical Engineering Angleški jezik Slovenski jezik © authors, 2025 Neznano 2025-08-11 10:45:49 2025-08-11 11:15:53 2025-10-24 03:53:44 0000-00-00 00:00:00 2025 0 0 Str. 1-9 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-05-21 624 doi.org/10.53243/ICBBG2025-13 244927235 242778115 ICBBG2025-13.pdf ICBBG2025-13.pdf 1 4FA46AF3503F9782913E7420B8ACD659 9f908cab38d5df8df9571da01793135fb3846e58e9f5783fa32ff2731463c2e4 95a165de-768f-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34227 https://doi.org/doi.org/10.53243/ICBBG2025-13 0 c2067dd5-7693-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34228 Zavod za gradbeništvo Slovenije 0 0 0
