“…Cation exchange causes the flocculation and agglomeration of soil particles with the consumption of Ca2+, which fills the pores and further strengthens the aggregate structure [28]. As these hydrates crystallize and harden over time, the engineering behaviors of stabilized soil will be improved (e.g., strength, permeability and swelling) and contaminants will be immobilized [29][30][31][32].…”

Cd contamination of sediments poses a serious threat to the global environment human health. A detail and comprehensive investigation of cadmium (Cd) pollution in the surface sediments of Dongjiaogou River was carried out. Concentration analysis of Cd in various depth and locations was conducted based on 82 samples collected from the river surface sediments where the sediments is up to 353 mg/kg. Subsequently, stabilization/solidification (S/S) method, an effective method of improving the engineering properties of sediments and encapsulating contaminants, was applied in these sediments. According to the results, the Cd pollutant was treated effectively by S/S method, which verifies the feasibility to mitigate the hazards caused by Cd in those sediments from the river. Furthermore, the S/S sediments are favorable as filling material in the road for both recycling and construction.
