Abstract
This study investigates how chloride-based salts affect the immobilization and leaching of Cu, Zn, and Pb from cement hydrates and analyzes the associated internal changes in crystalline phase. Results showed that the amount of Pb leached is highest in mortar when it contacts with CaCl2solution.A key reason for this outcome is thatcalcium silicate hydrate (CSH)has the lowest Pb adsorption in CaCl2 solution.Exposure to MgCl2 solution resulted in the decomposition of most portlandite to form brucite in mortars, lowering the pH to ∼9. This caused the lowest leaching rate of Cu, Zn, and Pb inMgCl2solution.
