Abstract
The cement production process is one of the most energy-consuming processes and has a strong environmental impact. The main impact on the energy consumption of cement production is the burning process of cement clinker in a rotary kiln, and the energy costs associated with burning cement clinker constitute 50-75% of cement production costs. Therefore, most of the activities in the cement industry are concerned with focusing on the process of lowering energy intensity. The use of new, energy-saving production technologies, and increasing the share of alternative fuels from waste in the process of cocombustion with coal in a rotary kiln requires the circulation of volatile components that are dangerous for the process: chlorine and sulfur. Therefore, there is a problem of managing significant amounts of the obtained byproduct. This chapter presents the physical and chemical properties of the formed cement kiln dusts (CKDs) and the possibilities of their development in construction.
