High volumes of dredged soil generated during dredging operations often create major disposal problems and environmental concerns since the soil is generally weak and unsuitable for construction. However, by incorporating sustainable additives such as Ground Granulated Blast Furnace Slag (GGBS), an industrial byproduct of the iron and steel industry, the strength, stability, and durability of dredged soil can be significantly improved, making it more suitable for geotechnical applications. In this study, dredged soil collected from Ponnani Harbor and Ayikkara Harbor is blended with varying percentages of GGBS (5%, 10%, 15%, and 20%) and its effect on engineering properties is analyzed through tests such as the direct shear test. In line with the principles of sustainable infrastructure, which emphasize the reuse of waste materials, dredged soil—often considered waste—can thus be converted into a valuable resource. Additionally, the use of cockle shell powder (CSP), derived from waste shells, is explored as another additive, with mixtures containing different proportions (2.5%, 5%, 7.5%, and 10%) being tested to evaluate improvements in mechanical properties. These methods demonstrate the potential of transforming dredged soil into a sustainable material suitable for applications such as road construction and embankments.
