PROCÉDÉ DE CARBONATATION ACCÉLÉRÉE ET SA MISE EN OEUVRE DANS UN PROCÉDÉ DE VALORISATION DE DÉCHETS DE BÉTON ET DE REJETS GAZEUX INDUSTRIELS
An accelerated carbonatation method including the following steps: a) providing recycled concrete granulates with a grain size smaller than or equal to a value V1 being between 1 mm and 6 mm, in other words a 0/V1 sand; b) performing on the 0/V1 sand a separation step by defining a granulometric cut of a determined value V2 being between 0.1 mm and 0.2 mm so as to obtain: a 1st fraction whose grain size is less than V2, and a 2nd fraction whose grain size is between V2 and V1; c) subjecting the 2nd fraction to an accelerated carbonatation step in a dynamic carbonator so as to obtain carbonated recycled concrete granulates. Also, a method for valorizing concrete wastes and industrial gaseous discharges implementing the accelerated carbonatation method, in particular the gaseous discharges of a cement plant.
