Recent advances in concrete recycling technology focus on novel fragmentation techniques\nto obtain aggregate fractions with low cement matrix content. This study assesses the aggregate\nliberation effectiveness of four different treatment processes including standard and innovative\nconcrete fragmentation techniques. Lab-made concrete samples were subjected to either standard\nmechanical crushing technique (SMT) or electrodynamic fragmentation (EDF). For both fragmentation\nprocesses, the influence of a microwave weakening pre-treatment technique (MWT) was investigated.\nA detailed analysis of the particle size distribution was carried out on samples after fragmentation.........................
