Accelerated Carbonation of Cement Kiln Dust and Lime Kiln

One of the ways to reduce CO 2 emissions from the cement industry is to react the produced CO 2 with alkaline wastes produced during the manufacturing of cement such as cement kiln dust (CKD) and lime kiln dust (LKD). CKD and LKD are finegrained, unreacted wastes obtained from the calcination of finely ground limestone fed into cement kilns.
