To provide fundamental data for processing methods aimed at recycling and reusing radioactive concrete, basic experiments were conducted to separate aggregates from simulated contaminated concrete using the heating-and-rubbing method. This study summarizes the aggregate recovery rates and the Cs removal rate obtained using the heating-and-rubbing method.
