The invention discloses an anti-radiation functional aggregate prepared from Cr-containing and Zn-containing electroplating sludge. By means of heavy metal elements including Cr and Zn, the anti-radiation functional aggregate has the beneficial effect that the anti-radiation functional aggregate has good shielding performance for high-energy rays, and a regenerated aggregate can have good anti-radiation performance; pulp wrapping processing is conducted on the regenerated aggregate through a vacuum stirring technology, and the surface structure of the aggregate is optimized; ultrahigh performance processing is conducted on the aggregate, subjected to pulp wrapping, through autoclaved curing, and the chemical property, the shielding performance and the heavy metal ion solidification effect of the anti-radiation functional aggregate are improved. The anti-radiation functional aggregate solves the problem that the uniformity of natural high-density ore anti-radiation concrete is poor, meanwhile, a large amount of heavy-metal-containing industrial sludge can be consumed, and the important significance in preparation of anti-radiation concrete and processing of the industrial sludge is achieved.
