Cement kiln dust (CKD) is a fine-grained solid by-product generated during the cement manufacturing process and captured by the facility's air pollution control system. Because much of the CKD is unreacted raw materials, it is often returned to the production process.
1912-1967 Glasgow Iron and Steel Co. 1967-1970 GI&SC / APCM joint venture. 1970-1974 APCM. The plant had a history similar to Coltness, initially making Colloseus activated slag cement, and then making clinker from the slag with rotary kiln(s), to make a PBFC product. The evidence for this consists of tangential references in the local press.
Iron and steel slag products are used in a variety of areas where their unique characteristics are put to effective use. The majority of the demand for these products comes from the field of cement. Approximately 40% of iron and steel slag products, and 60% of blast furnace slag, are used in cement.
By-pass cement kiln dust (CKD) is a fine-grained alkaline particulate material similar in appearance to Portland cement collected in the air-pollution control devices (such as cyclones, bag house or electrostatic precipitators) during the production of cement clinker.
