LARGE SCALE CARBONATION OF CONCRETE WASTE
The present invention concerns a method for recycling concrete aggregates from demolition waste (31), the method comprising the following steps: providing an individual fraction (11a, 11b, 11c, 11d) of concrete aggregates obtained from concrete waste (31) from a demolition site (1) with a defined grain size distribution d/D, measuring and adjusting a water content in said fraction of the concrete aggregates, introducing a defined amount of CO2 (21) into a reactor vessel (5, 5', 5", 5‴), introducing said individual fraction (11a) of concrete aggregates into the reactor vessel pre-filled with CO2 separately from other fractions (11b, 11c, 11d); controlled carbonation of the individual fraction (11a, 11b, 11c, 11d) of concrete aggregates in the reactor vessel resulting in a carbonated fraction (11) of concrete aggregates; removal of the carbonated fraction of concrete aggregates from the reactor vessel for subsequent use in the production of a new concrete composition (16).
