Abstract

The possibility of obtaining cement clinker using low-energy, resource-saving technologies has been studied. The composition of industrial waste for the low-energy production of portland cement clinker at factories in South Kazakhstan was analyzed. The possibility of replacing the deficient iron-containing corrective additive with “clinker of zinc ores” is shown. “Сlinker of zinc ores” performs several tasks as part of the raw charge: it is an iron correcting additive, it works as a mineralizer for clinker formation processes, it introduces coal into the charge and allows to reduce the consumption of natural fuel. The main idea of the study is the study of clay shales and the possibility of their application in the production of composite cements and the possibility of increasing their pozzolanic activity, as well as the ability to reduce greenhouse gas emissions by reducing the clinker component. The object of research is the study of chemical and mineralogical composition, physical-technical and technological properties, applied active mineral additives and the properties of composite cements. The received heat-treated clay shales of the mineral deposit show high pozzolanic activity, which allows them to be used as an active mineral additive in the production of composite portladcements.
