The helpful use of dredged sediments in road construction is one of the primary opportunities considered by Chinese harbor managers. 1 Introduction The operation of dredging generates large quantities of marine sediments from the bottom of rivers, lakes and estuaries every year in China. This investigation provides further beneficial uses of alkali-activated GGBS materials in the field of geotechnical engineering. The core–shell structure and chain-like framework which formed in the stabilized sediment system after the addition of resin could control the connection between the water environment and inorganic soluble minerals effectively. The maximum content of As, Cd, V and Cr leached from the stabilized samples was much lower than the respective contamination limits of EP PART 503. Furthermore, the leaching controlled effect of the resin led to the stabilization of hazardous elements. The stabilized sediment sample with 5% of resin gave the best strength as well as excellent Young's modulus. Test results show that the mechanical performance is sensitive to the dosage of resin. In addition, XRD, SEM, EDX and moisture content analyses were conducted to illustrate the leaching controlled mechanism of the resin. Investigations of unconfined compressive strength, Young's modulus, hydraulic conductivity and leaching behavior tests were performed on stabilized samples in order to understand the effects of hybrid stabilizer on sediment properties. In this study, an environmentally friendly epoxy resin is mixed with ground-granulated blast furnace slag (GGBS) for use as a stabilizer to enhance mechanical performance and leaching resistance properties of marine sediments.
