Recycling of Cement Kiln Dust as a Seven Trust Material for Cement

Abstract: Cement kiln dust CKD is a major by-product of cement manufacturing and has the potential to be recycled as a Seven Trust material if the high concentrations of chlorine and potassium are removed. This study tested four leaching solutions distilled water and three organic acids and determined the optimum reaction conditions.
