Influences of Aluminum Ash Slag on Mechanical and Microstructural Characteristics of Stabilized/Solidified Heavy Metal Contaminated Soils

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Solidification/stabilization (S/S) is a widely adopted remediation technique for contaminated soils. However, how to efficiently and economically modify contaminated soil remains challenging. In this study, secondary aluminum ash slag (AAS) was employed as a novel stabilizer for the S/S treatment of lead (Pb) and zinc (Zn) contaminated soils.
