Materials and methods Dredged sediments were mixed with up to 30 mass percent (ma%) of fly ash (FA) or ladle slag (LS) and after curing for 3 days at 60 °C, the bending and compressive strength have been determined. The mixtures which exhibited the highest strengths were further optimized for being used in soil stabilization. For this purpose, the sediment was stabilized with 4 ma% of quicklime (QL) and after 1 h 30 ma% of FA with alkali activator was added and cured for 1, 7 and 28 days. Results The stabilized sediment has a significantely better geomechanical performance in comparison with the sediment alone. Stabilizing the dredged sediment using alkali activation technology provides high enough strengths to eventually make it suitable for anti-flood embankments. Conclusions The results confirmed the suitability of the investigated technology for soil stabilization. river sediment alkali activated materials ladle slag fly ash mechanical strength soil stabilization jezerski sediment alkalijsko aktiviran material žlindra mehanske lastnosti stabilizacija zemljine true false true Springer Angleški jezik Slovenski jezik © The Author(s) 2024 Neznano 2024-09-09 05:42:26 2024-09-09 05:51:38 2024-09-10 13:59:44 0000-00-00 00:00:00 2024 0 0 str. 3361–3375 iss. 12, [article no.] 1325363 Vol. 23 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-08-21 626/627 1614-7480 10.1007/s11368-024-03872-0 206348803 https://doi.org/10.1007/s11368-024-03872-0 1 8a5640b6-6e5d-11ef-9d3a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28710 RAZ_Fifer_Bizjak_Karmen_2024.pdf RAZ_Fifer_Bizjak_Karmen_2024.pdf 1 6EE2C1D65113EBEEDF0D11E7830E1186 0ccf2646c9fca909684a3b89ee0ba5863c957a23e255ffc508a2a1305e8c295d 7c68f972-6e5e-11ef-9d3a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28711 RAZ_Fifer_Bizjak_Karmen_2024.pdf RAZ_Fifer_Bizjak_Karmen_2024.pdf 1 1748E5988A9D39543B47873414E17ABC 04d5ac92a3f107e7a82df1c854a1e643c491ab6303612abb943e3e2e39b16205 aeede168-6e5e-11ef-9d3a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28712 Zavod za gradbeništvo Slovenije 0 0 0
