The degrees of mineral carbonation in (a) construction and demolition waste (C&DW) and (b) a mixture of cement and fly ash were studied through a dynamic experimental method to determine the variation in the rate and extent of CO sequestration achievable under simulated outdoor conditions. A number of experiments were performed in a self-designed rotating batch reactor by churning the two samples together with CO, which was passed through the mixtures by using water vapor as the medium of transfer. At an injection flow rate of 1 L/min for CO, the theoretical extent of carbonation was observed to be 39.
