Abstract

During burning of Portland cement clinker, a large amount of both clinker and aspiration dust accumulates in electrostatic precipitators and rotary kilns; therefore, rational use of these products containing a certain portion of a complete raw material is an important task in the cement industry. It is noted that reuse of dust from electrostatic precipitators through recycling in the kiln is impossible, since it contains a high amount of alkali-containing impurities, and this will have a negative effect on the clinker quality. Therefore, the paper presents a practicable method of utilization of cement kiln dust in production of alkali-activated clinker-free binders and concrete based on these binders. The results obtained in the study of cement kiln dust are presented, and the energy dispersive and comparative analyses of the test powders are carried out. The results of chemical analysis are used to determine the relationship between oxides in the form of appropriate moduli and saturation factor. Recipes for alkali-activated binders are developed, and their properties are studied.
