Use of cement kiln dust in blended cement concretes
Proceedings of the Institution of Civil Engineers - Construction Materials, 2010This paper reports results of a study conducted to evaluate certain mechanical properties and durability characteristics of blended cement concretes, such as silica fume, fly ash and blastfurnace slag, incorporating up to 15% cement kiln dust. The results indicate that the compressive strength of silica fume and fly ash cement concretes with up to 10%

Microwave Radiometry for Cement Kiln Temperature Measurements
Journal of Microwave Power and Electromagnetic Energy, 2005The maximum temperature inside a cement kiln is a critical operating parameter, but is often difficult or impossible to measure. We present here the first data that show a correlation between cement kiln temperature measured using a microwave radiometer and product chemistry over an eight-hour period. The microwave radiometer senses radiation in the 12-

The Lining for Rotary Cement Kilns
Refractories and Industrial Ceramics, 2001The main accent in the study of cement clinker-based refractory materials was placed on an optimum choice of the clinker-to-cement proportion, on a rational chemical, mineral, and granulometric composition of the clinker, on the development of techniques for laying and fixing the lining, on an optimum choice of water-to-cement ratio, on the use of ...

Removal of Heavy Metals by Cement Kiln Dust
Bulletin of Environmental Contamination and Toxicology, 1997Heavy metals and other toxic pollutants are considered extremely pernicious because they are toxic, nondegradable, and environmentally persistent (Weng C.H., 1994). Electroplating, metal finishing and or leather tanning are producing wastewater streams contaminated with heavy metals such as chromium, zinc, cadmium, lead, nickel, and mercury.

A dynamic model of a cement kiln
Automatica, 1972A cement kiln is a counter-flow type of process in which a complex series of exothermic and endothermic reactions take place. To understand its behavior and to provide a means of improving computer control, a dynamic partial differential model of the kiln has been developed.

Soil Modification by Cement Kiln Dust
Journal of Materials in Civil Engineering, 1995Cement kiln dust (CKD) is a waste by-product of portland cement manufacture. This material poses a health hazard, storage problem, and a potential pollution source. Consuming such material in civil engineering works to upgrade marginal materials would help solve some of these problems.

Beneficial Uses of Cement Kiln Dust
2008 IEEE Cement Industry Technical Conference Record, 2008Cement manufacturing is a critically important industry in the United States and throughout the world. In 2006, U.S. cement plants produced 99.8 million metric tons of cement. Worldwide production accounted for about 2.5 billion metric tons. As with most large manufacturing industries, by-product materials are generated. These industrial by-product and
