Abstract (en)
[origin: CA3225877A1] The invention relates to an accelerated carbonation process which comprises the following steps: a) providing recycled concrete aggregates with a particle size less than or equal to a value V1 of between 1 mm and 6 mm, in other words a 0/V1 sand; b) carrying out a separation step on the 0/V1 sand by defining a particle size cut-off with a value V2 of between 0.1 mm and 0.2 mm in such a way as to obtain: - a first fraction with a particle size less than V2, and - a second fraction with a particle size between V2 and V1; and c) subjecting the second fraction to an accelerated carbonation step in a dynamic carbonator (11) in order to obtain carbonated recycled concrete aggregates. The invention also relates to a process for upcycling concrete waste and industrial waste gases, in particular waste gases from cement works, using the accelerated carbonation process.
