 This study investigated the feasibility of using CKD blends in the manufacturing of cement. It found that the use of CKD blend can improve the properties of cement, such as compressive strength, by increasing the proportion of CKD. Additionally, the use of CKD blends can reduce the amount of free lime, loss on ignition, and insoluble residue in the cement.
