Effect of the accelerated carbonation treatment on the recycled sand physicochemical characteristics through the rolling carbonation process

摘要

Accelerated carbonation was employed to improve the physicochemical properties of the recycled sand through CO2 sequestration by a method called rolling carbonation. The carbonation process was fully evaluated by varying some parameters such (i) moisture of the sand, (ii) rotation speed, (iii) recycled sand amount in the reactor, (iv) initial internal pressure, and (v) partial CO2 pressure.
