Re: differences bitween (CKD) cement kiln dust and (CBPD) cement bypass dust. Maso, Cement kiln dust is the dust which passes out of the top of the preheater with the exhaust gases, or more typically out of the back of a long wet or long dry kiln. Bypass dust is the dust that is drawn out of the kiln inlet when some kiln exit gases are extracted between the kiln and preheater to break the. The aim of this study was to investigate the use of cement kiln dust (CKD) as a cementitious material in concrete and mortar. CKD was added to concrete and mortar mixtures to study its effect on the strength and on the ability of the cover zone to absorb water, an important factor in the deterioration process Abstract Solid waste management is one of the major environmental concerns around the world. Cement kiln dust (KKD), also known as by-pass dust, is a by-product of cement manufacturing. The environmental concerns related to Portland cement production, emission and disposal of CKD is becoming progressively significant. CKD is fine-grained, particulate material chiefly composed of oxidized. However, CKD has been utilized in several purposes such as in the United States where approximately 60% of the total produced CKD returned to cement manufacturing after further process [6]
