Abstract：Effects of sintering system on the mineral composition and properties of aggregates prepared by electroplating sludge rich in Cr,Zn and other heavy metals were studied.The sintering mechanism of antiradiation functional aggregate prepared by electroplating sludge was discussed.The anti-radiation functional aggregates with γ-ray shielding performance were successfully prepared by precalcination-calcination.The linear weakness coefficient(μ) of 0.662 MeV γ-ray for the aggregates was greater than or equal to 0.220 cm-1.Single grain compressive strength was greater than or equal to 5.00 MPa,and bulk density was 2.60 g/cm3.The leaching concentration of heavy metals could meet the environmental security requirements.
