This study proposed a new curing agent consisting of slag and desulfurization gypsum industrial waste to solidify Cr(VI)-contaminated soils and prevent its migration and bioaccumulation in the ecosphere. The curing agent dosage of 10-30% resulted in a Cr(VI) toxic leaching concentration, compressive strength, and hydraulic conductivity range of 0.118-5.824 mg/L, 2.70-10.22 MPa, and 1.70 x 10-9-1.37 x 10-6 cm/s, respectively. Following four dry and wet cycles, the dosage of the curing agent was found to be 20-30% to achieve minimum environmental safety requirements. Cr(VI) in the cured specimen...
