SEPARATION OF HARDENED CONCRETE PASTE FROM AGGREGATE
Method for separating hydrated concrete paste from aggregate comprising the steps of providing a feedstock comprising waste concrete with a D10 ≥ 0.1 mm and a D90 ≤ 100 mm, passing the feedstock, a water containing liquid and carbon dioxide into a fragmentation vessel, where the wet feedstock is subjected to electric-pulse fragmentation, withdrawing fragmented solid material from the fragmentation vessel, separating the fragmented solid material from admixed liquid phase, separating the fragmented solid material into a fine fraction with a maximum particle size of 250 µm to provide the carbonated recycled concrete paste and a coarse fraction, recycling the coarse fraction into the fragmentation vessel and/or discharging the coarse fraction as clean aggregate, use of the recycled concrete paste obtained thereby as supplementary cementitious material or filler.
