REVIEW ON RADIOACTIVE CONCRETE RECYCLING METHODS

Abstract. The article presents the way in which recycled concrete aggregates’ properties influence the features of the new concrete. There are discussed classic and innovative methods for radioactive concrete recycling, having as main purpose the increase of the radioactive waste volume. The authors perform an evaluation of the national level technique status, and also a comparative analysis between radioactive concrete recycling techniques.

Oct 25, 2017  Concrete is, after water, the second most widely used material on the planet. The manufacturing of concrete generates about 4.5 percent of the world’s human-induced carbon dioxide emissions. Replacing even a small portion of concrete with irradiated plastic could thus help reduce the cement industry’s global carbon footprint.
