This paper investigates the feasibility of using cement kiln dust (CKD) as a partial substitute of cement in the production of solid cement bricks. Two types of cement (i.e., ordinary Portland cement and sulfate resisting cement) and two cement contents (i.e., 150 and 200 kg/m 3) were used. A total of twelve mixes were prepared with 0%, 30% and ...
