This study investigates the efficiency of the electrofragmentation technology for the up-cycling of concrete waste. Tests were performed at continuous scale at various operating conditions and showed that high liberation and recovery rates of aggregates were obtained after just one treatment step performed at 1 kWh/t. These results confirmed then the potential of the electrofragmentation technology for the selective recovery of the natural aggregates contained in concrete waste.

Mots clés: Electrofragmentation; construction and demolition waste; selective fragmentation
