Modern trends in the development of the global cement industry are to reduce the energy intensity of Portland cement production and reduce the environmental burden on the environment. The most negative side factors of production should be attributed to the large output of greenhouse gases. An effective solution to these problems may be the production of mixed binders based on less energy-intensive local cements modified by the addition of clinker when grinding. It is shown that the reduction of fuel costs up to 20–40% when manufacturing Portland cement is achieved by combining the thermal and technological cycles of processes for obtaining Portland cement clinker and lime-silica binder of low-temperature firing. Additional thermal effect is achieved through the use of fuel-containing fly ashes of thermal power plants or waste of coal improvement. The combined method of production of two types of binders makes it possible to reduce carbon dioxide emissions by 22–60% per final mixed product compared to traditional production of Portland cement clinker. Also, this method makes it possible to significantly expand the possibilities of utilization of large-capacity technogenic waste – fuel ashes of thermal power plants and waste of coal enrichment. The efficiency of the proposed technology is confirmed by the production of a factory pilot batch of lime-ash cement in the amount of 60 tons.
