Key Points
Leaching of Pb, Cd, and Hg reduced by more than 90%, indicating effective metal immobilization.
Strength tests indicate 10% increase in specimens with 50% replacement of granulated blast furnace slag.
X-ray diffraction analysis revealed denser microstructure due to C-S-H gel formation with added binders.
Findings highlight potential for improved waste treatment methods in managing designated waste materials.
