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.

Methods Of Concrete Recycling

Methods Of Concrete Recycling. 2020-5-10Recycled concrete aggregate RCA differ from natural aggregate as the former contains attached mortar. Given the recycling process of RCA, that is, by crushing, the microstructure presents several disadvantages, such as porosity, micro-cracks, as well as weak interface transition ones ITZs, which will also damage the mechanical properties and durability ...

Radioactive waste management involves a series of stages, including planning and preparation, treatment, packaging, storage and disposal. Most radioactive wastes are managed in the following way: Planning and preparation: Wherever possible, sites aim to reduce the amount of waste they produce. They also plan how to manage waste before it arises.
